Design and Analysis of a Muffler for Engine Exhaust Noise and Heat Reduction

Engine exhaust noise and heat are significant sources of emissions in the environment. Engine exhaust systems are designed to minimize noise and heat while maintaining the necessary db levels and sound quality, as well as emissions in accordance with environmental regulations. Mufflers remain an integral portion of the IC engine arrangement are widely used in IC engine exhaust arrangements to reduce sound generated by engine exhaust gases as well as to reduce heat. The most efficient way to reduce noise and heat is to install a exhaust muffler in the engine tail pipe. The aim of our project is to design and analysis an engine exhaust muffler for reducing exhaust noise and heat. Appropriate design and analysis would aid in the reduction of noise and heat, while at the same time, the backpressure generated by the muffler should not affect the engine's efficiency. 3D models are developed in Solid Works software before being exported to ANSYS FLUENT CFD software for review in this report. Pressure conditions will be defined as the inlet and outlet boundary conditions in ANSYS/FLUENT, respectively. Then, in the proposed model, the problem is solved to simulate internal fluid flow (exhaust gas). The simulation result and experimental results are compared.
