74th Annual Meeting of the APS Division of Fluid Dynamics

November 21-23, 2021
Phoenix Convention Center * Phoenix, Arizona


The 74th Annual Meeting of the American Physical Society's Division of Fluid Dynamics (DFD) will be held as an in-person meeting at the Phoenix Convention Center in Phoenix, Arizona, on November 21-23, 2021.

We recognize that local conditions regarding COVID-19 vary globally, and it may not be possible for all DFD members to travel to the Meeting. While the absence of an online option will be disappointing to some members, the Meeting will follow all applicable US Center for Disease Control and Arizona Department of Health guidelines to provide a safe and secure meeting environment. The primary value of the Annual Meeting is in the community that it fosters, so we encourage all members who are able to travel to the Meeting to join us in Phoenix and continue this valued tradition.
