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 30 June 2029.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 28 October 2029.

Abstract

When fluids like water and air flow over surfaces, the roughness of the surface can affect how they flow. Surface roughness influences flows around ship hulls, past iced airplane wings, through pipelines and over urban areas. Rough surfaces increase drag, which increases energy consumption and operating costs. Although rough-wall turbulence has been studied for decades, current prediction methods are largely…
