The Steady State Numerical Simulation of Nacelle Fluid and Temperature Field

YU Jian-zu

Abstract

The finite elements model of the nacelle is created using the non-structure grids by the finite volume method.Considering the real flow situation in the nacelle,the flow and heat transfer control equations are computed by the SIMPLE arithmetic,and the temperature field in the nacelle is analyzed.Further more,based on the problems in the existing design,the improved projects for the nacelle cooling situation are provided,and also the analysis of the projects.The simulation results have provided reference to the ameliorating design for the nacelle cooling system,which can ensure the engine working well,and have important practical meaning.
