CAE technique for low noise and high power engine in the exhaust system

摘要

To come up with quieter and higher-powered vehicles, it is necessary to derive the changed rate in the sound pressure at the tail pipe outlet port, and the influence to the power of the engine quickly and correctly by changing the specifications of the exhaust system. This is the report of the simulation technique which we established to obtain the values concerning this matter from the point of both acoustic and fluid engineering.
