Abstract

The present paper deals with the radial equilibrium problem of gas flow at the inlet and outlet of a wave rotor theoretically, presenting a method of solution. The salient feature of this method is that, in contrast to turbomachinery, the outlet flow parameters are related to those at inlet by the state characteristic (compatibility) equations of unsteady rotor flow. The numerical example has shown that the radial equilibrium effect plays a very important role in the design and performance of wave machinery and hence it is suggested that a complete gas dynamic design procedure of a wave machine should include two parts: (a) solution of the one-dimensional unsteady relative flow in rotor at the mean radius; (b) solution of the radial equilibrium problem of gas flow at the rotor inlet and outlet.
