针对游泳运动中关键的推进力和行进阻力力学问题,采用传统的试验研究方法具有成本高、可重复性低、无法解释本质机理等局限性。CFD仿真技术作为一种高效的流体问题研究手段,已经被国内外学者广泛应用于处理此类问题中。通过综合分析、归纳近20年来国内外关于CFD在游泳运动中应用的文献报道,从CFD仿真技术的特点及基本步骤出发,总结了实施该技术处理推进力和行进阻力问题的手段与成果,并探讨了相关的发展趋势,为我国游泳科研学者运用CFD仿真技术提供借鉴。

Aiming at analyzing the propulsive force and the hydrodynamic drag force in swimming research,the traditional experimental methods are limited by the high cost,the low duplication and the disability to interpret the fundamental dynamic mechanism.In recent decades,the CFD simulating technology,as an alternative effective method for fluid study,has been widely used in the swimming research.By dissecting the state of the art,prosperities and practical steps of the CFD are presented,and followed by summarizing the application methods and the corresponding results in the propulsive force and the hydrodynamic drag force aspects,respectively.Finally,the future development is proposed,which may be considered for domestic researchers.
