A simplified method of thermoacoustic engine analysis


A simplified method of thermoacoustic engine analysis is proposed. The main idea is that the thermoacoustic engine assumed as the acoustical circuit which consists of different components. Acoustic pressures, volume velocities at the two ends of any component and other engine parameters are computed by the transfer equations. Comparison results obtained by this method and by program code DeltaE are given.
