The 72nd Annual Meeting of the American Physical Society’s Division of Fluid Dynamics (DFD) will be held at the Washington State Convention Center in Seattle, Washington on November 23-26, 2019. The DFD annual meeting is one of the largest conferences in fluid dynamics, with 3000 or more attendees expected from around the world. The objective is to promote the advancement and dissemination of knowledge in all areas of fluid dynamics. Undergraduate and graduate students, postdoctoral researchers, university faculty, and researchers across government and industry are encouraged to share the latest developments in the field. The technical program features oral presentations, posters and videos of fluid flow, including mini-symposia on key topics. Below, please note the exciting new changes that will be taking effect this year in Seattle:

APS-DFD 2019 Seattle, WA. Annual Meeting will start on Saturday, Nov 23rd

For the first time in the history of the APS-DFD Annual Meeting, this year’s scientific sessions will start on Saturday Nov 23rd at 3 pm. This is to allow for an early finish of the meeting at or shortly after, noon on Tuesday, Nov 26th.

The parallel sessions that would have traditionally been scheduled on Tuesday afternoon will be scheduled on Saturday late afternoon, allowing more flexibility for travel to Seattle from Asia, Europe and the East Coast.

We anticipate that most APS-DFD attendees will be able to arrive in Seattle on Saturday morning or early afternoon and have time to go from the airport to the hotel, have some time to freshen up and walk to the Convention Center for registration and start of the Saturday sessions. If attendees prefer to arrive on Friday, Nov 22nd, the APS-DFD block rooms will be available at most area hotels.

The APS-DFD organizers expect that attendance will be much better for the Saturday afternoon sessions that would have been on Tuesday afternoon sessions, as seen in previous years. We do not want to put the meeting attendees in the difficult spot of having to decide between attending a significant part of the scientific program of the meeting or leaving town early to avoid being in an airport on Wednesday, the busiest day of air travel in the US.

Registration and Speaker ready room will be open early in the morning on Saturday, Nov 23rd, to welcome all attendees on the first day of the meeting. Exhibits will open on Sunday morning and will close on Tuesday morning, as usual.

Flash Presentations + Poster for APS-DFD 2019 Seattle, WA.

This year’s DFD meeting will pioneer Flash Presentations as a new presentation modality. Thus, submissions for Oral Presentations will fall along two choices:

• The traditional 12-minute presentation, or

• be considered for a 1-minute oral “Flash Presentation” with an accompanying poster presentation. Note that this option is only available for Oral submissions. Abstracts submitted as Poster will not be eligible for Flash Presentations.

The Flash Presentation sessions will take place on Monday afternoon in parallel in the three large invited session rooms. Each will consist of 90 1-minute presentations, with each presenter having a single PowerPoint slide, submitted in advance of the meeting, summarizing their work. To maximize the audience of these presentations, the sessions will be the only sessions scheduled for this time.

These sessions will be immediately followed by the poster session in the Exhibit Hall, where presenters can continue in-depth discussion of their work at their poster.

To be considered for a Flash Presentation, the submitter will check a box during submission oftheir oral abstract. If this box is not checked, then the abstract will be assigned a traditional Oral 12-minute presentation and not be considered for a Flash Presentation. A committee will review the submissions, and the top 270 will be placed into the Flash Presentation sessions. All other abstracts will be assigned to a traditional session in accordance with APS guidelines.

Come enjoy Washington State!
