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

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