对于复杂几何形状的三维流体流动，使用非正交的边界拟合网格可以很方便地进行预测。本文描述了一种用这种网格求解二维和三维问题运动方程的经济方法。计算因变量在网格上的位置，以及用来求解方程的方法，是开发一个成功的算法的关键问题；本文对这些问题进行了讨论。文中还给出了将所提出的方法应用于几个问题的结果。该方法适用于不以可压缩性影响为主的流动。
For three-dimensional fluid flows in complex geometries, it is convenient to make predictions using a non-orthogonal boundary-fitted mesh. The present paper describes an economical method of solving the equations of motion for two and three dimensional problems using such meshes. The locations on the mesh at which the depenent variables are calculated, and the methods used to solve the equations, are key issues in the development of a successful algorithm; these are discussed in the present paper. Results obtained when the proposed method is applied to several problems are also described. The method is intended for flows in which compressibility effects do not dominate.
