Annual report dates come from the budget period on your award notice. That date is not public, so it is not shown here.

How we got this date

NSF lists this award's end date as 31 March 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 July 2029.

Abstract

Vortex rings are swirling fluid structures that appear in many natural and engineering flows. Applications include the way the heart moves blood to how jets cool hot surfaces and control airflow over vehicles. The interactions of vortices with a surface determine how heat is transferred, how fluids mix, and how forces develop. Most current understanding of this process comes from studies of vortex rings interacting…
