Two good examples about conjugate heat transfer problem , one with cooling method , the other without cooling inside turbine blade were investigated 最后进一步地讨论了涡轮叶片中无冷却和有简单冷却通道情况下的流/热耦合计算。
Conjugate heat transfer calculation was carried out , with simple algorithm , studied up on boundary condition and modified pressure adapting algorithm , to give prediction on velocity field inside the disk cavity , the whole temperature field including fluid region and solid region , and heat transfer coefficient at fluid - solid interface . the simulation results indicate , ( 1 ) in rotor - stator disc cavity , the secondary flows near rotating disc stronger than which near state disc , keeps temperature of rotating disc lower than state disc ' s 为了使计算方法得到更多的算例验证,本次研究做了若干算例,文中选出其中四个算例进行分析,计算结果表明: ( 1 )在转静盘腔结构中,转盘表面的二次流大部分区域都比静盘表面的要强,所以转盘表面换热情况较好,转盘的总体温度水平要低于静盘。
