基于高性能并行计算的旋转网球空气动力学模拟
Aerodynamics Simulation for Rotational Tennis Based on High-performance Parallel Computation
摘要
Abstract
Based on the cluster architecture,hardware and software of Shuguang 5000A,the computational fluid dynamics method is used to investigate pressure distribution around the tennis surface under various speeds and rotational velocities.For the simulation study,the Realizable k-e turbulence model is utilized specially for the Magnus force of rotational tennis,a rotaling tennis aerodynamics simulation method is proposed.The air-pressure difference between the upper and lower surface of tennis increases with the increase of rotational velocity,and the enhanced Magnus effect makes the tennis fall down immediately.The increase of ball speed decreases the controllability of tennis and leads to the disorder of air flow around tennis.The drag coefficient and lift coefficient increase with the increase of ball speed and a bigger rotational velocity.Experimental results show that the computational accuracy and efficiency can be improved by the multinuclear parallel computation.关键词
