| Abstract: | This paper discusses the prediction of the exhaust aerodynamic noise of a diesel engine by using the characteristic method of calculating the nonsteady gas flow and the theory of sound radiation. By carrying on the simulation at various engine operating conditions, the authors have proved a good agreement of the calculated results with the experimental results. |
