    Abstract: 本研究係以數值分析方法研究層流衝擊 噴射流對以浮力趨動對流流場之影響。由計算 結果可知衝擊噴射流之影響甚鉅。其中衝擊噴 射流具有輔助或抵消浮力的作用,使得在穴內 之流場與溫度分布受到熱或冷衝擊噴射流的明 顯影響。本文亦同時考慮穴之長寬比為影響因 子。
    The influence of laminar impinging jet on the buoyancy driven convective flow field has been investigated numerically in this study. Computed results suggest that impinging jet has significant influence on the buoyancy-driven flow field. The impinging jet can aid or oppose buoyancy such that the flow pattern, and temperature distribution in the cavity are strongly affected by the heated or cooled impinging jet. Aspect ratio of the cavity is also an influence factor for the present analysis.
