In this paper, we investigate the possibility of using the wall ventilation flow to improve the aerodynamic characteristics of a generic rocket. Numerical simulation of a transonic compressible flow using commercial CFD software ANSYS Fluent was conducted for several transonic Mach numbers. The use of a ventilation wall affects the flow topology by weakening the shock wave structure and thus decreasing the pressure force impacting the rocket. For different transonic Mach numbers tested, the attenuation of the shock wave was found to be more significant at lower speeds. However, the modified geometry increases the recirculation region, which restrains the improvement of the drag coefficient. The use of this flow control method must be optimized to find an acceptable balance between the improvements made and the additional flow perturbations.
