This paper presents a new hybrid approach for prediction of noise radiation from engine exhaust systems. It couples the time domain analysis of the engine and the frequency domain analysis of the mu‚er, and has the advantages of both. In this approach, cylinder/cavity is analyzed in the time domain to calculate the exhaust mass ̄ux history at the exhaust valve by means of the method of characteristics, avoiding the tedious procedure of interpolation at every mesh point and solving a number of… CONTINUE READING
