Transmission Loss and Propogation of Higher Order Modes in A Muffler with Large Straight Pipe
碩士 === 逢甲大學 === 機械與電腦輔助工程學系 === 102 === This thesis is to investigate the transmission loss and high-order acoustic modes of the exhaust muffler of auxiliary power unit (APU) by using finite element analysis. To calculate the transfer impedance, the acoustic impedance of perforate plates and felt m...
