基于CFD的游泳比赛粘性阻力分析
|
Abstract:
竞赛的核心精神是对抗与公平，但显然从流体力学的角度来看，游泳比赛本身就存在着不公平性。鉴于此，利用Solidworks软件建立三维简化模型，并应用Autodesk CFD软件对游泳比赛各泳道的流场及粘性阻力进行分析。且提出了在游泳池壁附近加装类传动带装置，可有效减小各泳道粘性阻力的差值。
The core spirit of competition is confrontation and fairness. However, from the perspective of fluid mechanics, it’s obvious that swimming contest itself is unfair. In consideration of this situation, a simplified three-dimensional model is established by using Solidworks software, and the flow field and viscous resistance of swimming lanes are analyzed by using Autodesk CFD software. It is proposed that the difference of viscous resistance of swimming lanes can be effectively reduced by installing a belt-like device near the wall of swimming pool.
