Acoustic Simulation of Two-Dimensional Model of Intake Duct Based on Actran Software
Based on the classical JT15D aero engine model,Actran/TM module and Actran/DMG module in Actran software are used to simulate the acoustic propagation characteristics of the engine inlet.The simulation is based on two-dimensional model expansion.TM module is used to study the influence of different mesh types and mesh sizes on the simulation results.In addition,a two-dimensional model simulation based on Actran/DMG module was established,and a comparative study was conducted with the two-dimensional simulation data of Actran/TM module to establish the respective characteristics of the two simulation modules in the software in the aero engine inlet acoustic propagation simulation.
