摘要

新型超级冷却技术(NSCT)是一种基于热驱动理论的新型冷却技术

针对该技术的平均换热特性进行了实验研究

结果表明:随着浮力数Bu、旋转雷诺数Reω、进口冷气雷诺数Rez的不断增大

旋转条件下新型超级冷却技术的平均换热效果逐渐增强。将新型冷却技术与常规两种涡轮叶片冷却方式-肋强化冷却和冲击冷却的平均换热效果进行比较

得出结论:在实验范围内

新型超级冷却技术比另外两种冷却方式具有更优的换热效果。

Abstract

A New Super Cooling Technique based on thermally driven theory was studied further at the background of turbine blade’s cooling by Experiments.Experimental results show that the heat transfer effect of this new cooling technique is enhanced with increasing in buoyancy

rotational Reynolds number and cooling air Reynolds number

its cooling ability is better than those of the other two kinds of current blade cooling techniques.
