Overall Simulation of A Turbojet Engine Based on Through-Flow Modelling

摘要

This paper is devoted to the flow field calculation for an entire turbojet engine using a numerical simulation software, which was verified by many numerical examples of aeroengine.In the software, the unsteady Euler equation with viscosity force was occupied for the quasi 3-D simulation.In order to get more accurate results, many loss and deviation models with improved correlations are included, which are based on real 3D geometry of engine flow passage.With the help of this tool, the characteristics of the engine in design point as well as off-design point are obtained.To examine the reliability of the computation, results are compared with the experimental datas.Through the comparison, it will be demonstrated that this software is an essential and effective tool for overall engine analysis and matching of the gas turbine components.
