Abstract
This thesis is aimed at simulation of the acoustic and gas flow performance of intake and exhaust system components representative of large marine diesel engines. Modelling and simulation was conducted using 1D CFD in a ‘virtual’ test bench. An experimental acoustic transmission loss test bench (zero flow) was designed and developed to provide validation for the simulation. A finite element analysis of a large marine muffler’s shell was conducted to assess possible interactions.
