Abstract

In the present investigation, computational studies were made to obtain the influence of circular cavity on the performance of a mixed compression supersonic air-intake designed for Mach 2.2 with and without back pressure. Numerical simulation has been conducted with RANS solver by using k-w turbulence model. Starting characteristic of the intake is achieved by incorporation of a cavity of various radius on the second ramp at various locations. 12.2 % of increment in TPR is obtained with circular cavity of radius 1 mm at a location of X/L = 0.1468 on account of some increment in the FD with the cavity. Results obtained could be useful for further studies to improve the intake performance.
