An Initial Study of Finite Element Analysis on Sound Pressure and Pressure Drop on a Diesel Generator Sets

Abstract

This study is concern about the behavior of a diesel generator sets in terms of sound pressure level and pressure drop. Numerical study had been carried out by using simulation from the ANSYS software to obtain the sound pressure level and pressure drop across a duct silencer of a diesel generator sets. ANSYS Fluent and ANSYS Harmonic Responses was used to perform the simulation on the sound pressure level and pressure drop of the duct silencer. The design of the 3-dimensional model consists of splitter and rockwool as its porous medium. Observation was focused along the simulation process and detailed investigation has been carried out on the duct silencer. From the results obtained, there is noise reduction and pressure drop occur across the duct silencer and contour were observed clearly.
