| 摘 要： | 针对游泳中划水时手指应该张开与否的分歧,运用CFD数值模拟的方法,通过建立手掌和手指的简化模型,先后计算了手指分别张开不同角度及不同划水攻角时对应的阻力和阻力系数,计算结果表明手指张开角度越大其阻力和阻力系数越小。

| Abstract: | In order to clarify the bifurcation that it should or not splay fingers in swimming, this paper has applied the numerical simulation technique of CFD and based on the model of palm and fingers, the drags and corresponding coefficients were calculated in the case of different angles of flare and different angles of attack. As a result, it indicated that the more the flare angles the less the drag coefficients. |
