Surface Pressure Measurements on a Forebody Using Pressure Sensitive Paint

摘要

Pressure sensitive paint (PSP) gives the full-field pressure pattern on themodel surface with a high spatial resolution and is an alternative to traditionalpressure taps used in a wind tunnel model. This study determines surfacepressure patterns on the forebody of an AGARD B model in a compressibleflow and the data is in comparison with a numerical simulation using ANSYSFluent software. The lift and drag coefficients are calculated and comparedwith data in literature. The experiments use a blowdown wind tunnel. Thefreestream Mach number is 0.83 and the angle of attack ranges from -4° to8°. The difference between the results using PSP and the numericalsimulation is less than 5%.
