  2. Then the thermal visualizations of jet impingement cooling with single or double row holes inside semi - enclosed ribbed channel are measured by using infrared camera and the effects of flow and geometry parameters on convective heat coefficients are obtained. the results show that : the impingement cooling effectiveness of ribbed surface is affected greatly by the jet - to - surface spacing, and the best effectiveness is achieved under the jet - to - surface spacing equals to 1. the correlation formulas of impingement heat transfer characteristics to the parameters are finally concluded and in good agree with the experiment data

    最後，對單排、雙排沖擊孔試驗板在半封閉通道展開了流量系數的研究，在變化各種幾何因素及流動因素的情況下由實驗得出了沖擊孔流量系數值，討論並分析了各種因素對流量系數的影響程度，建立了沖擊孔流量系數的準則關系式，與實驗結果對比表明:該準則關系式與實驗實測數據吻合較好，精度較高，有較高的工程應用價值。
