Simulation of flow and heat transfer characteristics of laminated turbine blades with kerosene cooling channels

An air-kerosene thermal mass coupled turbine blade with kerosene microchannels added to the traditional laminated structure is proposed, and numerical simulations are carried out. The enhanced heat transfer mechanism of studied, influence different temperatures, blowing ratios, solid conductivity on blades analyzed. results show that adding can significantly reduce temperature change cooling gas direction inside laminate structure. Compared structure, improve performance blades, integrated efficiency increases by 31.7%. Moreover, when decreases from 400 K 300 K, 3.9%. Similar conclusions be obtained studying in ratio conductivity, respectively.
