【摘要】 采用数值模拟的方法对转动圆盘进行计算。为了克服计算过程中迭代发散的问题,将转动圆盘作为非定常流动进行计算,待计算到一定时间后,边界层速度场基本形成,再将所计算的非定常流场的结果作为定常流动的初始流场进行计算,从而使收敛过程稳定,有效的避免了计算发散。最后将数值模拟的结果和精确解的结果进行了比较,发现数值模拟结果与精确解相吻合。更多还原

【Abstract】 The rotor plate is calculated by the numerical simulation.As the convergent strategy,the rotor plate is calculated first as the unsteady flow case in order to overcome the iterative divergence during the calculation.After a period of time,when the velocity field of boundary layer is formed,the result of unsteady flow field is regarded as the initial flow field of steady flow and the calculation continues.This method can make the convergence process steady and effectively avoid the divergence.The results of numerical simulation and accurate solutions are compared and it is found that they agree well.更多还原
