| 摘 要： | 笔者介绍了一种验证灰尘气体中驻点热流率增大机理的方法。在灰尘负荷率相同 ,微粒速度相近条件下完成激波管 2e区实验气流分别为亚声速与超声速的实验。实验结果表明 ,含灰气流中驻点热流率增大只与灰粒速度有关。

| Abstract: | A method for verifying mechanisms of increased heat transfer rate at stagnation point in dusty flow was introduced.The experiments with same dusty loading rate and with close particle velocities were performed at both subsonic and supersonic flowfield,respectively.The experimental results indicate that heating augmentations at stagnation point in dusty flow only depends on impact velocity of particles. |
