  1. The thermal visualizations of jet impingement cooling with single or double row holes inside semi - enclosed channel are measured by using infrared camera and then the impingement cooling heat transfer coefficients are deduced. the effects of flow and geometry parameters on convective heat coefficients are obtained. the results show that : for a single row normal impingement, the impingement cooling effectiveness is enhanced with the increase of impinging reynolds number or the decrease of hole space to diameter ratio, and the best effectiveness is achieved under the jet - to - surface spacing equals to 2 ; when the jet is oblique to the confined wall, the cooling effectiveness is weaken especially under the jet - to - surface spacing ratio is greater than 2 ; for double rows normal impingement cooling, the cooling effectiveness of rear row jet is weaker than the front row under lower impinging reynolds number or bigger jet - to - surface spacing

    對于單排垂直射流,沖擊冷卻效果隨射流雷諾數的增加、孔間距與直徑比的減小而得到提高,沖擊間距比為2時換熱效果最好;沖擊孔中心線向通道封閉一側傾斜后,射流沖擊冷卻的范圍變窄,當沖擊間距比大於2時駐點區的對流換熱能力明顯降低;對于雙排沖擊射流,孔排間距與直徑比的增加使沖擊冷卻范圍變大,但在兩排孔之間區域的對流換熱系數有所下降;在較小的沖擊射流雷諾數和較大的沖擊間距比下,後排射流的沖擊換熱效果要遜於前排射流。
  2. At the same time, the effects of dragging force from fall of hydrometeors and latent - heat release from phase transfer are tested. from the analyses we conclude that the distributing of the cloud particles relates with temperature closely. huanan heavy rainfall and mei - yu front heavy rainfall have mixed - phase process with vapor phase, liquid phase and ice phase

    詳細分析了形成降水的雲物理過程,探討了源匯項對水凝物的貢獻,並通過敏感性試驗,考察了雲物理過程對降水熱力動力過程的反饋作用,研究結果表明:華南暖區暴雨和長江梅雨鋒暴雨的雲物理過程具有汽、水、冰三相混合雲特徵。
