  1. All of the results indicated the turbulent boundary layer had been turned into the laminar layer. the skin friction coefficient drops rapidly. this result not only proved the phenomenon of reverse transition had occurred, but also showed that this condition was drag - reducing condition

    實驗結果表明板面附近的流動已由湍流流動轉變為層流流動,同時平板表面的摩擦系數較沒有溫度梯度時有大幅度下降,不僅證明了邊界層逆轉捩現象的存在,也說明了這種條件起到了減阻的效果。
