讨论了一类不确定运动磁流体动力学系统的有效数值方法。我们包括任意的不确定性的参数,然后描述一个随机配置方法来处理这种随机性。文中还讨论了该方法的数值模拟。我们发现参数分布的形状不仅影响均值和方差,而且影响解分布的形状。
We discuss an efficient numerical method for the uncertain kinematic magnetohydrodynamic system. We include aleatoric uncertainty in the parameters, and then describe a stochastic collocation method to handle this randomness. Numerical demonstrations of this method are discussed. We find that the shape of the parameter distributions affect not only the mean and variance, but also the shape of the solution distributions.
