- ( 3 ) special attentions are given to flow and heat transfer in the rotating disk cavity which are associated with the rotational reynolds number , and which the mass flow rate coefficient cw
( 3 )在研究旋转雷诺数re _对该盘腔流动和换热的影响的基础上，进一步研究了流量系数cw对流动和换热的影响。 - The results indicate that : the high positioned air inflow do good to heat transfer in rotator disk ; different size of radial outflow have small effects on flow and heat transfer ; the heat transfer near rotating disk increases as rotating reynold number increases or non - dimensional mass flow rate increases
结果表明，高位轴向进气对转盘换热有利；不同的径向出口大小对盘腔内的流动换热影响不大；随旋转雷诺数和无量纲质量流量增加，转盘盘面的换热效果增强。 - ( 2 ) the results reveal that the pre - swirl ratio has a great influence on the flow field of the rotating disk , even greater than the rotational reynolds number , and an initial constant is induced in moment coefficient cm and average nusselt number nuave correlations , which does not exist in the case of without pre - swirl
( 2 )分析了预旋系数_ r对该旋转盘腔流场的影响，定义了一个新的压力系数c _ p ，该压力系数c _ p沿径向位置的变化对特定的旋转雷诺数re _是一个常数。 - ( 1 ) taking the new br 700 gas turbine which is developed by rolls - royce deutshland as research object , the numerical simulation has been applied to the new structure of rotating disk system with pre - swirl nozzles on the rotating disk with ? turbulence model and with a new hybrid grid
( 1 )本文以rrd公司新研制的机种br700为研究对象，采用-湍流模型对带有预旋的新型旋转盘腔内的流动进行了数值计算。在旋转盘的计算中提出了一种新的网格剖分方法，计算的旋转雷诺数达到1 . 0 10 ~ 8 。 - 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。
