Kai Schneider

摘要:

综述了计算复杂几何条件下受限流体和等离子体流动的浸没边界方法。描述了体积惩罚技术的数学原理,并给出了一维Dirichlet和Neumann边界条件的简单例子。在两个和三个空间维度的流体和等离子体湍流的应用程序说明的适用性和效率的方法在计算复杂的几何形状,例如在环形几何形状与非对称极向截面的流动。

英文摘要:

Immersed boundary methods for computing confined fluid and plasma flows in complex geometries are reviewed. The mathematical principle of the volume penalization technique is described and simple examples for imposing Dirichlet and Neumann boundary conditions in one dimension are given. Applications for fluid and plasma turbulence in two and three space dimensions illustrate the applicability and the efficiency of the method in computing flows in complex geometries, for example in toroidal geometries with asymmetric poloidal cross-sections.
