Abstract :
The research of the exhaust gas injection of a gas turbine has been done with the numerical simulation and experimental study method in this thesis. It comes to the proposal of adding diversion bell mouth to the mixing section entrance. And then it determines three kinds of plans by changing the distance from nozzle to the injection section entrance, in order to observe the changes of the injection coefficient. The experiments also have been done to validate the numerical simulation results, and the tally situation is good.
