Numerical simulations and wind tunnel experiments over three-dimensional double compression ramps in supersonic flow at Mach 3 were carried out to investigate three-dimensional effects on finite-span ramp models. A three-dimensional Reynolds-Averaged Navier-Stokes solver was used to obtain steady solutions. Four cases were studied and each case has two different second-stage angles of 30 and 45 degrees with and without sidewall. Surface aerodynamic coefficients including the heat flux coefficient and flow fields on both center and side lines of 3D compression ramp were compared with the experimental results. Numerical Schlieren contours were well validated with Schlieren images that obtained from a model aerodynamic facility. A parametric study shows that the three-dimensional effect is mainly caused by the flow leakage from the separation bubble around the ramp corner.
