Abstract
A numerical study was conducted to simulate the heat transfer from an array of jets onto an impingement surface typical of those found on aircraft wing/slat surfaces. The study used the commercially available computational fluid dynamics software FLUENT to model the different hot-jet arrangements that included 1) a single array of jets, 2) two staggered arrays of jets at different stagger angles (10 and 20 degrees), and 3) a case with an etched surface. The main Undings of the study reveal that the single array and the array with a 20 degree stagger yield better surface heat transfer than the 10 degree stagger. The etched surface or inner liner yields almost 2-3 times better surface heat transfer than the others, thus making it a favorable choice for increasing surface heat transfer.
