摘要
本文以煤油为工质进行了窄缝射流冲击传热实验研究。对射流冲击平板时的局部传热分布做了测定，并发现了局部换热强化现象，这是由于存在壁面射流区边界层流动由层流向湍流的过渡。实验采用宽度为１２５μｍ的窄缝喷嘴，射流出口速度为６～１４ｍ／ｓ，雷诺数Ｒｅ范围６００～１２００。
Measurements were made to investigate the local behavior of heat transfer coefficient with submerged slot jets. The experiments were performed with kerosene jets impinging on vertical constant-heat-flux surface from meso-scale slot nozzle of 125 μm in width in the ranges of jet velocity from 6 m/s to 14 -m/s. Heat transfer coefficient at stagnation line was collected and correlated as a function of jet Reynolds number. Lateral distribution of heat transfer coefficients was also determined and correlated.
