blade cooling
blades cooling
Examples
- Cooling air enters at the center of the system and leaves through the holes in the rotor and clearance between rotor and shroud
针对转速、冷却气体流量以及叶片冷却孔的存在与否对腔内流动特性的影响进行了分析。 - In this paper . the conclusion of this paper has utility meaning in analysis on turbine blades cooling after some proper correcting of the geometry structure and boundary conditions
由于所采用的结构及计算域近似涡轮叶片的冷却形式(主流加热，内流通道冷却) ，因此这种方法经过进一步的改进，可用于涡轮叶片冷却的计算研究。 - Measured hole mass flows and a constant static pressure mixing analysis , together with the measured losses , allowed the decomposition of the losses into three distinct entropy generation mechanisms : loss generation within the hole , loss generation due to the mixing of the coolant with the mainstream , and change in secondary loss generation in the " blade passage
论文还进行了叶片冷却孔质量流的测量与常静压气流混合分析，结合前述气动力损失和冷却空气损耗的测量结果表明，端壁气膜冷却的综合损失明显地由三个部分组成：叶片冷却孔内产生的损失；由于冷却空气与主流热空气的混合产生的损失；二次流的变化产生的损失。 - 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。
