摘要
介绍了STAR -CD软件包所采用的控制方程、湍流模型和数值模拟技术。模拟了有出口旋转挡板的拉瓦尔喷管的超声速流场 ,分析了出口旋转挡板转动对超声速喷管流场速度。
Basic equations,turbulence models,numerical simulation technologies used in a STAR-CD software package are described. Supersonic flow of a Lavar nozzle with a rotatable outlet baffle is simulated. The dynamic effects of the rotating baffle on supersonic nozzle flow parameters such as velocity, pressure, Mach number are analyzed.
