摘　　要：平板表面开Ｖ形纵向沟槽，与光滑板进行流动阻力对比试验，结果表明，表面开沟槽以后具有明显的减阻效果，其减阻程度取决于表面所开纵向沟槽的几何特性。在实验范围内，０１ｍｍ沟槽减阻效果最佳，减阻率可达１０％。Flow resistance of longtitudinal grooved flats is experimentally studied and compared with that of smooth flat.It was shown that V-profile longtitudinal grooves have a noticeable effect on antifriction.The drag reduction depends on the geometric character of grooves.In the experimental range,the grooves of 0 1mm width have the best antifriction effect which is up to 10 percent.
