Experimental testing and CFD simulation to enhance the performance of existing 3-wheeler muffler

Heat Power Enginering, Mechanical Engineering

A muffler is a device used to reduce the noise and vibration of gas emitted by internal combustion engine. So, it becomes necessary equipment in automobile to have a proper emission of gases to surrounding. Due to improper design some muffler decreases the mass flow rate due to which there is increase in fuel consumption, large pressure drops across its cross section and higher knock sensitivity. Thus, recent research is being performed to increase the mass flow rate and decrease the pressure drop using the concept of perforation in CFD simulation in ANSYS software. In present project existing 3-wheeler vehicle muffler and modified is experimentally tested to determine the mass flow rate, velocity and temperature and also simulation is performed in CFD to validate the experimental results.
