摘要
用数值模拟方法研究了大钝头体外形(双子星座飞船)在超声速下俯仰振动的绕流特性,数值模拟的出发方程为三维全N-S方程,格式为二阶迎风TVD格式,研究结果给出了物体在俯仰振动过程中激波、分离结构和物面压力分布等非定常特征。
Flow field characteristics over an oscillating blunt body(Capsule-type vehicle)was investigated by numerical method.In this study,two second order implicit TVD(total variation diminishing scheme)scheme was used to solve full Navier-Stokes equations.The results have shown some very important information about flow over an oscillating blunt body,such as unsteady separation,shock and pressure distributions on the surface.
