Experiments are performed to study the characteristics of rectangular cavity flows. Mean and fluctuating surface pressure in a Mach 1.28 turbulent flow past rectangular cavities are obtained, The cavity length-to-depth ratio (L/D) is varied from 2.43 to 43.00 while the length-to-width ratio (L/W) is 0.5, 1.0 and 2.0. Three-diuiensioal effect is significant on the trailing edge vortex near the trailing edge of the cavity which affects the peak pressure ahead the rear face, pressure gradient and levels of pressure fluctuation near the trailing edge, particularly for closed and transitional cavity flows. The length-to-width ratio and Mach number may be important for the definition of critical length-to-depth ratio for the cavity flow field models.
