Two-dimensional heat flux distribution around cavities on flat plate models was measured by IR camera at a Mach number of 10 and angle of attack of 35 degrees. Based on the obtained data, a correlation study was attempted assuming that the magnitude of the wake heating depends on the resonant frequency in the cavity. The result shows that shear layer instability oscillation dominantly affect the amount of the heat transfer and the transition within the cavity and along the cavity wake flow.
