| Abstract: | Numerical simulation of the 3-D flow field inside a radial flow turbine used in the micro gas turbine was presented in this paper.Based on the simulation results analysis,it is found that the design parameter"t" in the design of the impeller is very important and has a great impact on the flow field inside the impeller and thus the efficiency of the turbine.Correlation between the efficiency of the turbine and the design parameter "t" was obtained with numerical experiments in an attempt to optimize the design of the impeller.Results indicate that the efficiency of the radial flow turbine has been increased by over 2%. |
