Abstract: Square tabs were placed on the base of an ellipsoidal centerbody (CB) in short annular diffusers. Tests were conducted in subsonic swirling flow with an inlet Reynolds number of 1 أ— 105. The tabs, with a projected ...

Abstract: Short annular diffusers with negative wall angles were evaluated numerically and experimentally with up to 40 deg inlet swirl at an inlet Reynolds number of Ret ≈ 1.4 أ— 105 and Mach number of Mt ≈ 0.16. The 80% ...

Abstract: Effusion cooling has been a popular technology integrated into the design of gas turbine combustor liners. A staggering amount of research was completed that quantified performance with respect to operating conditions and ...

Abstract: The accurate prediction of drag caused by bluff bodies present in aerospace applications, particularly at high angles of attack, was a challenge. An experimental and numerical investigation of a nacelle intended for ...
