Abstract�� Numerical simulation was used to investigate a new compound cooling system, which combines micro channel and film cooling together in a guide turbine vane. Research was focused on the optimization design of these new organizational structures, in order to discuss the different effect on the characteristics of flow resistance and heat transfer. In these designed structures, branching channel structure in balancing cooling efficiency and the pressure loss has good effects. The computational results also show that the cooling efficiency of this compound cooling structure is higher than the cast-cooling blade. The prospect of the compound structure applied to turbine cooling system is huge.
Keywords�� micro channel   film cooling   cooling efficiency   pressure loss
