説明
The influences of the molecular weight and total temperature of a primary gas on the flow fields of constant-area mixing tubes for ejector-jets were investigated. First, in order to investigate the exit choke, parametric studies were carried out for the exit-choke phenomena in the constant-area mixing tubes by using a one-dimensional model. The effects of the incoming Mach number, wall friction, expansion ratio of a primary nozzle, and specific heat ratio on the exit-choke phenomena were reported. Moreover, flow fields having primary flows with high total temperatures were investigated by CFD. The transition points from the exit-choke mode to the free-jet choke mode obtained by CFD were in good agreement with those obtained by the one-dimensional model. The pressure recovery performances in both choke modes were compared. The decrease in the static pressure at the exit of the subsonic diffuser attached downstream of the mixing tube was observed.
