CHO, WONBEOM. Double-Fin Induced Shock Wave/Turbulent Boundary Layer Interactions over a Cylindrical Surface. (Under the direction of Dr. Venkateswaran Narayanaswamy). Double sharp-fin induced shock wave/turbulent boundary layer interactions (SBLI) over a cylindrical surface have been scarcely investigated despite its significant influence on the maneuverability of missile-like projectiles. As the importance of the super/hypersonic missiles increases, it is inevitable to understand and resolve the SBLI over cylindrical surfaces. The purpose of this study is to understand the complex flow field of the double-fin induced SBLI over a cylindrical surface using pressure sensitive paint (PSP) measurements. The experiment explores the surface pressure field of the double-fin induced crossing SBLI with a leading edge of 10° at Mach 2.5 freestream flow. Conventional PSP and PC-PSP measurements were performed to obtain the mean and the unsteady pressure field. The interaction of the two shock structures from the two fins showed more complex pressure field than the result of the single fin induced SBLI. Also, due to the influence of the curvature surface, the pressure field was found to have different characteristics from the previous research that was conducted on a flat plate. The cylindrical surface led the shock structure to lose its strength on the surface, which results in comparatively simple interactions at downstream. © Copyright 2020 by Wonbeom Cho All Rights Reserved Double-Fin Induced Shock Wave/Turbulent Boundary Layer Interactions over a Cylindrical Surface
