Abstract:Real gas effect has great impact on unsteady flow behaviors in wave rotor refrigerator (WRR). In this work, the main thermal separation effect and propagation speed of gasdynamic wave of real gases are briefly studied. Numerical results have shown the large deviations between perfect gas model and real gas model for gasdynamic waves. A corrected wave diagram of WRR has been achieved based on real gas PVT relations, through which the problem of offset design of port timing can be completely solved.
