Wave rotors used for expansion refrigeration technology

Wave rotor is an unsteady flow device in whose passages pressured streams directly contact and exchange the energy due to the movement of pressure waves.A novel refrigeration apparatus named pressure exchanging refrigerator(PER) is developed by using four-port through flow(TF) wave rotors.The operating procedure and refrigeration principle are investigated based on one-dimensional unsteady flow theory,and the fluidic behavior of PER is also analyzed by means of computational fluid dynamics(CFD) .A basic lim...
