Aerodynamic Characteristics of Low Pressure Turbine under the Condition of Altitude Low Reynolds Number
Low pressure turbine(LPT) is an important component of aeroengine. The performance of LPT greatly influences the thrust-weight ratio and specific fuel consumption of aeroengine. It is imperative to investigate the flow and heat transfer characteristics in LPT for improving the aeroengine performance...

It is imperative to investigate the flow and heat transfer characteristics in LPT for improving the aeroengine performance research. Flow characteristics of an aeroengine LPT under altitude low Reynolds number are investigated by conjugate heat transfer methodology, meanwhile the effects of Reynolds number on the LPT efficiency and characteristics of flow are discussed in detail. The results indicate that, with the increasing of Reynolds number( |
