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.
