Numerical Analysis of Internal Flow in Mufflers with Complex Structures
This paper builds three-dimensional finite volume models for 4 different mufflers. Internal flow numerical analysis for mufflers is carried out with computational fluid dynamics software. Velocity field and pressure field are obtained to analyze the airflow influences on muffler performances. The corresponding regularities are obtained from simulation results, which provide a method for design optimization of mufflers.
