【Abstract】

<正>Unsteady shock wave buffet phenomenon on the upper surface of supercritical airfoils is predicted by IDDES hybrid methods.The geometry is an OAT15A airfoil at Mach number of 0.73 and angle of attack of 3.5°s.Dissipation-adaptive functions are introduced into high-order TVD methods.Prediction successfully cap-
