ABSTRACT
Two-wheeler silencers are used to silence the noise generated by engine while throwing out hot flue gases from the combustion chamber. The technique of silencing the noise is to pass flue gases through the silencer and reduce the flow speed. Hence the noise gets silenced. It also helps to discharge hot flue gases into atmosphere. Inside the silencer the flue gas allows to flow through different sections. During this flow the nature of flow needs to study well to understand the silencing phenomenon. CFD Analysis will help to learn this flow. Practically it is very critical to study flue gas flow inside the silencer. Hence CFD method is very popular and widely used in research and development of silencer.
In this review paper, we have studied literature of two-wheeler silencer. The temperature distribution, pressure variation, velocity gradient and the turbulence etc. are studied well to know the phenomenon of silencing the sound produced due to exhaust gases. Also, the improvements in design can be suggested based on the CFD analysis. Keyword: - CFD Analysis1, Silencer2, Temperature Distribution3, Heat transfer4.
