摘要

在本研究中,对流体在喷嘴内的流动状态进行了详细的分析。结果表明,喷管截面的变化规律不仅取决于流动速度的变化情况,还与其他状态参数,特别是马赫数有关。最后,通过对拉瓦尔喷管的仿真与理论分析对比,验证了仿真的正确性和数值模拟在实际工程中的可行性。

Fluid Flow Situation in the Nozzle of the Theoretical Analysis and Numerical Simulation
In this study, the flow of the fluid in the nozzle status were analyzed in detail. The results indicated that the changing rule of the nozzle cross section not only depends on the change situation of the velocity of flow, but also related to other state parameters, especially the Mach number. Finally, the correctness of the simulation and the feasibility of numerical simulation in practical engineering were proved by comparing the simulation of laval nozzle with the theoretical analysis of it.
