| Abstract: | Upon an analysis for turbulent jet mixing process in the mixing chamber of ejector, the hypothesis
of universal ejection characteristics developed by Abramovich is used to build up the integral equa-
tions. To verigy the integral method, two samples of non-isoenergetic turbulent flow mixing in a con-
stant area duct are computed and the temperature profiles are compared with the experimental data.
The flow field in the mixing chamber of an ejector is also calculated to present the velocity distribution
at several locations and pressure variations along the axis. |
