A method for calculating the performance of ejector nozzles
Abstract
The conventional assumption that secondary flow is a one-dimensional isentropic and that the pressure of both primary and secondary flow are equal has been modified in this paper. The pressure of primary and secondary is calculated by means of the relation between front and back parameters of the shock or Mach shock, and the ejector nozzle performance is determined using the equations between the inlet section and other characteristic sections. Calculation results of this paper have been verified by means of experimental data, and quite good agreement is obtained.
