Numerical simulation of flow control by a heat pulse under aerodynamic hysteresis in supersonic flow over an axisymmetric body with annular cavity

Abstract

A numerical simulation of flow control by an artificial heat actuator is presented. Investigation is performed for supersonic flow over an axisymmetric annular cavity under aerodynamic hysteresis conditions. The simulation is carried out using the FlowVision computational software package. The comparison of results of numerical simulation and experimental values is performed. The influence of position, power and width of heat pulse on the gas flow is studied.
