The PI proposes to make use of the facilities of the Radial Jet Reattachment Laboratory to perform exploratory studies on non-steady submerged radial jet impingement heat transfer. Prior studies by the PI on steady radial jet impingement resulted in very high heat transfer rates. Studies of non- steady non-radial jets by other investigators have demonstrated enhanced heat transfer performance. There is thus a good possibility that a non-steady radial jet may also offer enhanced heat transfer performance compared to conventional jets and steady radial jets.

课题负责人建议利用径向射流再附着实验室的设施，对非定常浸没径向射流冲击传热进行探索性研究。 PI 之前对稳定径向射流冲击的研究导致了非常高的传热速率。其他研究人员对非稳态非径向射流的研究表明传热性能增强。因此，与传统射流和稳定径向射流相比，非稳定径向射流也很有可能提供增强的传热性能。
