| 9. | 4 ) in a pre - swirl rotator - stator cavities with discrete pre - swirl nozzles and blade - cooling entry holes , the influences of pre - swirl angle and flow parameter on the flow and heat transfer characteristics were numerically investigated . the correlation for average nusselt number vs rotating reynold number or non - dimensional mass flowrate were established . the results show that : advantage of per - swirl inflow is the effect of cooling the blade - cooling entry holes ; pre - swirl inflow increases heat transfer in rotating disk of pre - swirl chamber ; as pre - swirl angle increases , local nusselt number decreases in pre - swirl chamber ; the temperature of stator of inner rotator - stator chamber and per - swirl chamber decreases as rotating reynold number increases ; when the axial mass flowrate maintains constant , heat transfer in the rotating disk of inner rotator - stator cavities does n ' t change as per - swirl mass flowrate increases , while heat transfer in the rotating disk of per - swirl chamber increases ; when the pre - swirl mass flowrate maintains constant , change of the axial mass flowrate has effect on the whole cavity
结果表明，预旋进气的优点在于增强了叶片冷却孔附近的对流换热效果，局部努谢尔数随预旋角的增大而有所减小；随旋转雷诺数的增加，不论是内转静腔室还是预旋腔室的静盘上的温度都不同程度的降低：当轴向中心进气质量流量不变时，随预旋进气的质量流量增加，内转静腔室的转盘盘面上的换热基本没有变化，而预旋腔室的转盘盘面上的换热效果增强；当预旋进气质量流量不变时，轴向中心进气的质量流量的改变对整个盘腔都有影响。 |
