Analysis of Various Automotive Mufflers: Computational Fluid Dynamics Approach

Muffler contributes extensively to decrease the backpressure and the noise pollution. It is essential to compare and display the overall performance of muffler system. This paper offers the results of the performance of an actual and modified automotive muffler system. The results of the automotive mufflers performance analysis are presented and a comparison is made to the decrease of backpressure and to increase the efficiency. Muffler modelling are performed in SolidWorks software and simulation analysis performed in ANSYS CFD (Fluid Flow) tool. The main purpose of this project is to optimize the automotive muffler through changing its internal designs to decrease the backpressure. Three designs are made with same dimensions and different internal designs are analysed in ANSYS CFD tool. Finally, the results are discussed in detail and the performance of the automotive muffler is showed in different variations.
