摘要
本研究以數值模擬的方式，詳細探討等溫以及熱毛細條件之下的沾濕抑制現象。液珠周遭的空氣，因為受到移動平板的剪應力或是熱毛細對流的作用，而流動到液珠與平板之間的間隙薄膜內，於是造成液珠與平板的沾濕抑制。
等溫條件下，雷諾數可對應於移動平板所造成的剪應力影響，韋伯數可代表不同流體的液珠之變形程度。熱毛細條件下，馬洛哥尼數可對應於溫差所造成的熱毛細對流影響，毛細數可代表不同流體的液珠之變形程度。對於相同的流體，較大的雷諾數或是馬諾哥尼數，都可造成較大的沾濕抑制。在相同的移動平板速度下，具有較大韋伯數的液珠；以及在相同溫差下，具有較大毛細數的液珠，其自由表面頂點的內凹現象都會較明顯。在等溫以及熱毛細條件下，當兩板距離減少時，可以獲得更明顯的非沾濕效應。
熱毛細非沾濕現象，只存在於將熱液珠靠近冷端牆的條件之下；反之，若以冷液珠靠近熱端牆，則無熱毛細沾濕抑制的現象出現。
