Optimization Design of Cooling Structure of Marine Gas Turbine Enclosure
The numerical simulation of marine gas turbine enclosure is performed,and the air flow distribution inside the enclosure and the defect of excessive temperature on enclosure wall surface are obtained.On the above basis,the optimization design of cooling structure of marine gas turbine is made.A branch structure is arranged inside the enclosure to improve the air flow direction;the exhaust gas ejector is installed outside the enclosure to cool the enclosure and reduce the energy consumption;the back edge slitting treatment of exhaust gas ejector nozzle is given to increase its ejection efficiency.The results show that the optimization design made can meet the cooling requirements of marine gas turbine enclosure.
