摘　　要：通过直接求解原始变量法的NS方程并应用运动网格技术对静止水中的振荡圆柱粘流场进行了数值模拟,计算了KC数在4种流态区下的振荡圆柱流场并分析了对圆柱受力的影响。与文献结果的比较说明本文所建模型是合理的,可用于相关问题的研究。Numerical simulation of oscillating cylinder in water at rest is done by RANS equation and dynamic mesh method.And flow of KC number at four flow form is computed and the influence of force on cylinder is analysed. The comparison with literature shows rationality of model established in the paper and can be used in study of relative problem.
