ABSTRACT

Aerodynamic parameters and stability of a near-wall flow over wavy plates of varying shapes in the free stream of Mach = 6 are investigated by means of numerical simulations. The wavy wall produces a stabilizing effect on a highspeed boundary layer by reducing second-mode instability amplitudes that may eventually delay the laminar-turbulent transition onset. However, the wavyness changes an aerodynamic drag of the surface. In this work a dependency of the stabilizing effect and aerodynamic parameters on the wavy wall shape are investigated. The simulations are done by integrating Navier-Stokes equations using an in-house HSFlow solver, which implements an implicit finite-volume shock-capturing method with the second-order approximation in space and time. Second-mode instabilities are excited by a high-frequency actuator of suction-blowing type placed on the wall. It is shown that with an increasing number of cavities the stabilizing effect is enhanced while the total aerodynamic drag coefficient reaches a certain level. This study helps to clarify robustness of the wavy wall stabilization concept at high speeds.
