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 November 2027.
NSF rules say the final report is due no later than 120 days after that.
So the final report is due by 29 March 2028.

Abstract

Flow boiling and condensation are crucial to the efficient and safe operation of electronics cooling, power generation, refrigeration, water purification, chemical processing, and among others. Two-phase flows are also subject to a wide range of instabilities at the liquid-vapor interface. These instabilities can lead to significant thermal performance degradation, reducing heat transfer coefficient, increasing…
