| Abstract: | This paper introduces a muffler design method and its performance simulation.This method gives the preliminary sketch of the muffler with transfer matrix method at first, and then attains the optimized design of the muffler by means of performance simulation with the CFD software.This software GT-Power is a new simulation tool based on one-dimensional fluid dynamics developed for the performance simulation of engine system including exhaust system parts such as muffler. This paper discusses the software application to the fluid dynamics and acoustics the performance of muffler.The results of the simulation example show the good prediction ability of the method. |
