Summer 2024 Newsletter

A Message From the Chair

Anette (Peko) Hosoi
Massachusetts Institute of Technology

Welcome to the 2024 edition of the Division of Fluid Dynamics Spring/Summer Newsletter. 

 

I would like to begin by expressing my deep appreciation to everyone who contributed to making the 2023 meeting in Washington, DC, a tremendous success. It was wonderful to see the meeting return to pre-pandemic levels of vibrancy and engagement. I also want to take this opportunity to thank all of the committee chairs and committee members who work tirelessly behind the scenes to ensure that our division runs smoothly.

 

In 2023, we launched an exciting new initiative to bring flow physics to the public via the Traveling Gallery of Fluid Motion. This program, which features both science and art inspired by fluid mechanics, was showcased at the National Academy of Sciences’ cultural programs gallery in Washington, DC. We are looking forward to the next installment in Salt Lake City. Additionally, DFD introduced the first in what we hope will be a series of APS webinars on the societal impact of fluid mechanics. The topic of this first panel was “Fluid Dynamics for Human Health,” highlighting the impact of fluid mechanics on healthcare and well-being.

 

Writing this message has also motivated me to reflect on the decades I have spent with the DFD community. I attended my first APS DFD meeting in Syracuse in 1996, and I have never missed a DFD meeting since. I have always loved the egalitarian culture of the meeting, where everyone gets a 10-minute talk, regardless of whether they are an undergraduate or a Nobel Prize winner. I am filled with gratitude when I think back on the mentorship, counsel, support, and inspiration I have received from junior and senior colleagues alike. Looking ahead, I see the same wonderful, vibrant community that drew me in back in 1996. This level of engagement also brings a unique and welcome challenge: the growth of our annual meeting. As of April 2024, DFD is the second-largest division in APS. The accompanying growth in the number of parallel sessions at the annual DFD meeting since 1996 is shown below.

Those 14 sessions in 1996 have blossomed to 40+ parallel sessions today; at this scale there are very few convention centers in the U.S. that are large enough to host our annual meeting.¹  Having served in the Chair line of the Executive Committee for the past two and a half years, I now appreciate that we are living on the edge: every year there is some uncertainty about whether we will be able to reserve a sufficiently large space.²  

 

Given these constraints, the data suggest that we are approaching a breaking point.³ Some features of the meeting may need to change, and I very much hope that we will be able to preserve the important aspects of our culture as we evolve. We as a community should think carefully about the things we value most in our meetings and the features we would like to prioritize. Before making any decisions about the meeting format, we would like to gather as much data as we can.

 

To this end, the DFD leadership has encouraged the Local Organizing Committees of the next few meetings to use a small part of each annual meeting to pilot different formats. Ideally, these pilots will explore strategies to address the large number of parallel sessions while amplifying the most valuable aspects of the meeting. We have also added two ad hoc members to the Program Committee to provide insights and advice. After each of these pilots, we will solicit feedback from the community to assess what works (and what does not) for DFD. During this period of experimentation, we very much hope that you will participate in the pilots, provide honest feedback, and be open-minded in assessing your experiences.

As a first step, we polled the community last Fall to understand what is most important to our membership in our meetings.  Overwhelmingly, the top response was “Interacting with colleagues in-person.” This response strongly resonates with me. The opportunity to see friends and colleagues every November, to hear about their work, their lives and families, their challenges, and their brilliant contributions to fluid mechanics is something I would never trade. Clearly any changes in format need to preserve, or even enhance, these in-person interactions.

 

In that spirit, I am delighted to provide a sneak peek into the Salt Lake City pilot. To simultaneously boost the audience size (one of the other highly rated attributes in last year’s poll) and increase in-person interactions, the Program Committee has proposed DFD-Interact sessions, which will take place on Sunday morning. Instead of 10-minute talks, the format will comprise a series of flash talks (similar to the popular flash talk sessions at the Seattle meeting) combined with one-on-one and small group discussions at posters or electronic presentations. These sessions will be curated to highlight particularly exciting and compelling work from the contributed oral abstracts. I am grateful to the Local Organizers and the Program Committee for their work in creating this pilot, and I am very much looking forward to attending the DFD-Interact sessions and hearing your feedback.

 

We have a few years to experiment before the number of parallel sessions becomes a crisis; we also know that DFD is a community of creative problem solvers and we are confident that the meeting will evolve to become more vibrant, inclusive, and scientifically stimulating than ever.

---

¹Note that the issue is not the number of attendees; it is the large number of parallel sessions associated with the DFD meeting format.
²Currently we are reserving venues almost 10 years in advance in order to ensure that we have access to the largest convention centers.
³One possibility would be to increase the length of the meeting, but registration costs would necessarily increase to cover the cost of the venue. Nonetheless, extending the length of the meeting is something we could consider. 
⁴We received 441 responses to the poll.

Note from the Annual Meeting Local Organizing Committee 

Henry Fu
University of Utah

Marc Calaf
University of Utah

We are excited to welcome the DFD 2024 Annual Meeting to Salt Lake City! We hope you enjoy the cultural, dining, and entertainment options close to the convention center, and perhaps even have a chance to visit the many natural sights, including numerous ski resorts and biking/hiking trails just minutes away from downtown, and five national parks within five hours of the city. Who said the best ideas only come while sitting in the lab? 

 

At the meeting this year, we will have a scientific program featuring awards and invited talks, minisymposia, focus sessions, and contributed oral and poster presentations at the high level you have come to expect from DFD meetings. In addition, on Sunday morning we are excited to pilot DFD-Interact sessions, which are designed to foster in-depth interaction with research and broaden audiences for each presentation. Instead of hosting 40-some parallel rooms of contributed talks, we will present about 20 parallel rooms, each with about 20 flash talks for poster or interactive e-poster presentations. 

This format will allow plenty of time for one-on-one and small group discussions. Fewer rooms mean larger audiences, and the DFD-Interact rooms will be thematically curated to highlight the most exciting submissions from the pool of oral contributed abstracts. We are thrilled to host these DFD-Interact sessions to enhance your science experience during DFD 2024, and we hope you have a wonderful stay in beautiful Salt Lake City.

Highlights of the 2023 DFD Annual Meeting

Ken Kiger
Co-Chair, 76th Annual Meeting of the APS Division of Fluid Dynamics
University of Maryland

Michael Plesniak
Co-Chair, 76th Annual Meeting of the APS Division of Fluid Dynamics
George Washington University

The Division of Fluid Dynamics held its 76th Annual Meeting at the Walter E. Washington Convention Center in Washington, DC in November 2023. The Convention Center is a light-filled public space that displays the country’s most extensive public art collection housed outside of a museum, making for a pleasant experience for attendees.  

The 2023 DFD meeting was a huge success, with more than 3,700 in attendance. The meeting included four award lectures, twelve plenary invited talks, four minisymposia, and three focus sessions. A unique focus session on Culinary Fluid Dynamics illustrated the many ways in which fluid dynamics touches all aspects of life, including food, and was accompanied by demonstrations in the exhibitors’ space.  

Although DFD has outgrown most venues in which to hold a large reception with food and beverages, we found a way to offer both a reception and access to one of the most iconic venues in Washington, DC, the Smithsonian National Air and Space Museum. The division hosted Sunday’s Conference Reception at the Convention Center with light appetizers and drinks. Then, on Monday evening, all registrants and their guests enjoyed exclusive access to the newly renovated National Air and Space Museum. Another special event on Monday evening was the Traveling Gallery of Fluid Motion Reception in the Great Hall of the National Academy of Sciences Building, an event seamlessly blending the worlds of art and science. The exhibition "Chaosmosis: Assigning Rhythm to the Turbulent" at the Cultural Programs of the National Academy of Sciences provided a unique opportunity to connect with innovative artists while chatting with scientists and exchanging creative ideas.   

 

The DFD meeting provided opportunities for young investigators and students to learn about funding and career opportunities in academia and industry. A panel of early- career award winners provided insights into managing funded research programs and achieving success. The 2023 meeting also placed a strong emphasis on Diversity, Equity, and Inclusion (DEI), with a dedicated abstract category and featured workshops such as All the Faces of Fluid Dynamics and Underrepresented Minorities in Research, and a minisymposium on The Stories of Women in Fluids.  

Overall, the 2023 DFD meeting was a resounding success with among the highest number of attendees and abstracts in the wonderful setting of the nation’s capital.  And the weather was also beautiful!

DFDiversity Dispatch

Rodolfo Ostilla Mónico
University of Cádiz
Chair, DFD Diversity & Inclusion Committee

 

Margaret Byron
Pennsylvania State University
Vice-Chair, DFD Diversity & Inclusion Committee

Did you know that only 15% of DFD membership identifies as women? And of these, approximately one third have considered leaving their profession due to family/work-life balance considerations?

 

While it will take time to address systemic barriers, the DFD D&I committee is working to identify and remove obstacles that prevent the division from fully welcoming and including all its members – and we need your help! Do you know of current procedures or policies that make the community less accessible or inclusive? Are there specific issues you would like to see addressed? Please email us at aps.dfd.dei@gmail.com! 

 

We are working with the current Executive Committee to build structurally sustainable practices that improve the climate for everyone. We are also coordinating with D&I committees in other APS divisions to identify best practices and new ideas. If you are a member of another division (or another professional society that is doing great work in this area) and you know of a particularly effective intervention or program, we would love to hear from you!

 

We are also interested in hearing about existing grassroots efforts that may not be formally recognized in the meeting program. These might include informal meet-ups of particular identity groups, helpful Slack channels, social media groups, and other related activities. We would love to connect these groups with any support they might need, and compile a directory to share with members searching for community. 

 

You can reach us at aps.dfd.dei@gmail.com. Please do not hesitate to reach out!
