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 January 2031.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 31 May 2031.

Abstract

Turbulent fluid flow plays a central role in technologies encountered in daily life, including aircraft, automobile, and energy systems. The ability to predict the behavior of a turbulent flow near solid surfaces is important, because it affects drag, efficiency, and stability. The flow can separate from a solid surface in many practical situations. Separation creates complex motions that are difficult to predict.…
