A Pi-type mean flow acoustic engine CFD model was built and the operation performance of the engine was obtained. The acoustic characteristics and hydrodynamic characteristics were analyzed. Running the engine in the first hydrodynamic and acoustic mode is most efficient in converting energy. Pressure wave phase differences between two resonators were obtained and analyzed. Pi-type mean flow acoustic engine differs from cross-junction mean flow acoustic engine in phase lag.
