Keywords: wave rotor, shock waves, unsteady flow

In the wave rotor design, significant importance has to be stressed upon the exact estimation of pressure wave generation and propagation, which is far more difficult than that in ordinary shock tube operation due to complexity of inner flow wave dynamics. In the present paper, some of our results from 2D numerical simulation and experimental visualization are introduced to clarify aspects of the wave rotor inner flow phenomena, including the interaction effect of adjacent passages.
