Summer 2025 Newsletter

Letter From the Chair

Jonathan B. Freund
University of Illinois Urbana–Champaign

Our 2025 edition of the Division of Fluid Dynamics Spring/Summer Newsletter comes at a time when our members have been sharing many concerns. Availability of funding — already a point of stress in so many science careers — will likely diminish, and even the very fabric of the university system in the U.S. seems at risk, further hampered by new frictions imposed on international study and collaboration.  Insular thinking and politically motivated protectionism puts strength from scientific exchange at risk.

So, what can be done? I wish this was easy to answer with more than platitudes. As a start, I try myself to recognize that far more of what we value remains than what has already been lost, so it is not time to accept or let fear paralyze action. Personally, I have become increasingly engaged in government, visiting congressional offices with APS and personally contacting elected representatives (e.g., A Call to Action | American Physical Society). Uncertainty can be met with focus on values and community, as we advocate for science and scientists as best we can.  

We need to do a better job communicating the impact of flow physics on people’s lives. Our Societal Impact of Fluid Dynamics webinar series is intended to seed such thinking. As science itself is being questioned, we should be on the lookout for opportunities to embrace those who would aid us if only we could explain things well enough to them. Impact will be broadest if we take on the onus of meeting people where they are in their understanding rather than where we might hope them to be.

While I deem the motivations that spawned ongoing DEI efforts to be an absolute good, it can also be true at the same time that the corresponding initiatives have not yet been broadly executed or communicated in the best way to achieve their goals, so we should be flexible as we actively build paths to belonging and community for all.  

A comfort I find — especially over summer — is reading our DFD-associated Physical Review Fluids, the storied Journal of Fluid Mechanics, Annual Review of Fluid Mechanics, and all the other journals that serve our membership. I am sure that I will again be marveling at how vibrant the field remains despite its long history and today’s challenges. At least the laws of flow physics are secure! Still, there is much work for us to do in collaboration as we seek to understand and describe them, which I look forward to doing with you in Houston. 

Community continues to be a goal of the DFD-Interact sessions, which will be refined in Houston based on feedback from their pilot last year in Salt Lake City. They are designed to foster in-depth interaction between more of our members. Our early-career researchers — the future of our community — were particularly supportive of their continuation. In November, I’m eager to hear your feedback and more ideas about how we can defend and strengthen DFD.

APS responds to the current crisis

APS continues to take action to counteract threats to science funding, and we wanted to ensure the fluid dynamics community is aware of these efforts and poised to help. 

• The new APS in Action hub mobilizes members, and serves as a primary messaging platform, including remarks from the Global Physics Summit town hall. 

• APS has waived membership fees for scientists harmed by federal actions, and filed a legal brief in support of federal science agency employees. 

• DFD members can participate! We encourage you to stand up for science by meeting with your congressional offices. Visit our toolkit to learn how. You can also ask Congress to reject the proposed cuts in the president’s fiscal year 2026 budget and share these resources with your professional and personal networks. 

APS also has resources to promote inclusive physics, advocate and amplify the voice for physics in public policy, prepare physicists for careers, and foster dissemination and connections in physics communities.

A note from the Local Organizing Committee APS DFD Annual Meeting 2025 

William Anderson
University of Texas, Dallas 

Paul Krueger
University of North Texas

Howdy folks! A hearty Texas shoutout to our APS DFD community as we look forward to welcoming you to Houston for the 2025 annual meeting. The conference venue is the George R. Brown Convention Center, which borders the Discovery Green, a beautiful urban park, and is surrounded by enjoyable food and entertainment. We’re hoping for some mild Texas fall weather to support some outdoor activities and socializing at the conference.

We are looking forward to an exciting slate of invited speakers, mini-symposia, and focus sessions, and especially, hearing from each of you during the contributed oral and poster sessions. 

This year, building on the broadly positive feedback last year, we will continue DFD-Interact this year as well, and will expand it to two sessions on Sunday. Similar to last year, each session will have around 40 parallel rooms with 20 talks in each room. To help facilitate interaction, only 10 submissions will be presented at a time, starting with a flash talk, and then individual presentations at posters or interactive e-posters throughout the room. Then the presenters will rotate halfway through the session to allow presenters to also interact with others in the session. The sessions will be organized thematically to highlight some of the most exciting submissions and facilitate small group discussions with the presenters.

All of the meeting rooms and exhibits will be on the same floor of the convention center to facilitate easy navigation during the event and promote collaborative engagement among attendees. Be on the lookout for the finalized schedule in the coming weeks, and we are eagerly waiting to see you in November.

Highlights of the 2024 DFD Annual Meeting

Marc Calaf
Co-Chair, 77th Annual Meeting of the APS Division of Fluid Dynamics
University of Utah

Henry Fu
Co-Chair, 77th Annual Meeting of the APS Division of Fluid Dynamics
University of Utah

The Division of Fluid Dynamics held its 77th Annual Meeting at the Salt Palace Convention Center in Salt Lake City, UT in November 2024. The Convention Center is conveniently located to the airport and downtown Salt Lake City. 

The 2024 DFD meeting was attended by 3000 people. It provided a venue for the high quality and cutting edge fluid dynamics research that we have come to expect, including four award lectures, twelve plenary invited talks, three minisymposia, and two focus sessions. This year, we piloted the new DFD Interact presentation format, which consists of thematically curated rooms of 20 flash presentations followed by person-to-person engagement at posters or e-posters. Our goal was to broaden audiences and encourage more networking and interaction around invited abstracts, and based on survey feedback the DFD Interact sessions were largely successful. The DFD Interact format will be continued and improved over the next meetings and may provide a way to alleviate the requirement for a large number of concurrent rooms that has started to restrict the selection of sites for future DFD meetings.

In addition to the core scientific program and usual Sunday evening reception, we provided meeting-goers the opportunity to visit the Leonardo Museum in Salt Lake City on Monday evening.  Inspired by Leonardo da Vinci, the Leonardo museum houses a varied collection of science and engineering-related exhibits, including one on aerodynamics, and of particular note hosted this year’s Traveling Gallery of Fluid Motion exhibit, “Spiraling Upwards,”  from November 1, 2024 to January 31, 2025.  

The DFD meeting provided opportunities for all of our young investigators and students to learn about funding and career opportunities in academia and industry. A panel of early- career award winners gave junior and soon-to-be faculty members advice on funding opportunities and establishing independent research programs.  Workshops such as All the Faces of Fluid Dynamics and Underrepresented Minorities in Research, and student-mentor meeting events aimed to promote and welcome researchers of all backgrounds into the exciting field of fluid dynamics.  

We were honored to help continue the tradition of making DFD meetings the best place to exchange scientific ideas, see old friends, and make new friends in the fluid dynamics community!

In Memoriam: Andreas Acrivos

The American Physical Society Division of Fluid Dynamics is sad to announce the passing of Professor Andreas Acrivos, one of the foremost scientists in the fields of rheology, chemical engineering, and fluid dynamics. Professor Acrivos passed away peacefully in the early morning of February 17, 2025 at his home on the Stanford campus.  He was 96 years old.
  
Born in Athens on June 13, 1928, Professor Acrivos emigrated to the United States to pursue studies in chemical engineering. He earned his bachelor's degree from Syracuse University in 1950 and continued his graduate studies at the University of Minnesota, where he received his master’s degree in 1951 and his Ph.D. in 1954. His academic career began at the University of California, Berkeley, in 1954, where he was appointed Assistant Professor and promoted to Professor in 1959. In 1962, he moved to Stanford University, where he played a pivotal role in the development of the chemical engineering program and served as department chair from 1972 to 1975.  

Professor Acrivos left Stanford in 1988 when he accepted the position of Albert Einstein Professor of Science and Engineering at the City College of New York. He was also appointed the Director of the Benjamin Levich Institute for Physico-Chemical Hydrodynamics at City College until his retirement in 2001. 

His research contributions covered a wide spectrum of topics, including high Reynolds number separated flows, interfacial effects including interfacial convection, drop deformation and breakup, and internal wave dynamics. However, he is best known for his masterful use of asymptotic methods in the analysis of heat and mass transport processes at high and low Reynolds number, and for his studies of the properties of suspensions, emulsions, and fiber-filled materials, which significantly influenced the understanding of their microstructure and microrheology. His work, in collaboration with Gadala-Maria and Leighton, on concentrated suspensions and shear-induced diffusion, changed the field in a radical way, and remains a cornerstone of modern rheology and the dynamics of flowing suspensions. Furthermore, his mentorship was crucial to the development of many distinguished scientists, such as J.D. Goddard, L.G. Leal, D. Barthes-Biesel, W.B. Russel, J.F. Brady, D. Leighton, and E.S.G. Shaqfeh, many of whom are or were at the forefront of rheology and fluid dynamics. 

One other legacy that he was proud of was the evolution of Physics of Fluids, which he edited for 17 years, from a journal in which fluid mechanics was a small section (5%) to a journal that prominently featured papers on plasma physics, to a separate journal that focused exclusively on fluid mechanics and was recognized at the conclusion of his editorship as one of the top publications in the field.  

Professor Acrivos was honored with numerous prestigious awards and distinctions, including the National Medal of Science (2001), recognizing his contributions to fluid mechanics and chemical engineering, the Fluid Dynamics Prize from the American Physical Society (1991), the Bingham Medal from the Society of Rheology (1994), and the G.I. Taylor Medal from the Society of Engineering Science (1988). In addition to these prestigious accolades, two significant awards have been established in his honor. These  include the Andreas Acrivos Award for Professional Progress in Chemical Engineering by the American Institute of Chemical Engineers (AIChE), recognizing outstanding professional achievements in the field of chemical engineering and the Andreas Acrivos Dissertation Award, presented by the American Physical Society to recognize outstanding dissertations in fluid dynamics.  He was a member of the National Academy of Sciences, the National Academy of Engineering, and the American Academy of Arts and Sciences.  

Professor Acrivos is survived by his wife Juana, his sister Acrivy Stavropoulos, niece Maria and nephew Andreas in Athens,  sister-in-law Lily Crespo Vivo, and family Armando and Antonieta Crespo, their children, grandchildren, and godchildren. He is also remembered by a host of graduate students, postdocs, fellow faculty and co-workers that benefited over so many years from his wisdom, mentorship and friendship.

--- L. Gary Leal and Eric S.G. Shaqfeh

Why study fluid dynamics?

Tim Colonius
California Institute of Technology
 
This coming fall, the DFD will host the third in an annual series of webinars on the societal relevance of fluid dynamics. The series examines how fluid dynamics shapes our world and improves lives, examining grand-challenge problems including climate, environment, clean energy, and resilient infrastructure.  

Moderated by DFD Executive Committee Members-at-Large, a panel of experts will discuss the state of the field, what drives their research agendas, and identifying fundamental fluid mechanics research topics that will be drivers for progress. The panel will also address questions and comments submitted by the global audience.  

Previous topics included The Fluid Dynamics of Human Health and Fluid Dynamics of Clean Energy Transition. The webinar is a great opportunity for early-career researchers to learn how to identify and discuss the broader impacts of fluid dynamics research. It is also designed to seed thinking about how to show all people — not just fluid mechanicians — why flow science is important to their lives.

This year’s topic will be The Fluid Dynamics of Disaster Prevention. Please watch your inbox for announcements and registration instructions for the fall webinar!
