Numerical Simulation of the Inner Flow Field and the Optimal Design of Hema-Type ATY Nozzle Based on Fluent

the inner flow fields of twelve Hema-type ATY nozzles which have different structure and parameters are simulated by the Fluent software, which is based on the CFD (Computational Fluid Dynamics) theory.Then the simulation results are analyzed，through wich the best designed nozzle is determined.
