真实的流动是用偏微分方程来描述的,在一般情况下,偏微分方程不能用解析法求解。通过将复杂的流动区域划分为许多小单元,这些方程可以用数值方法近似求解。由于其广泛的应用,数值流动计算(“计算流体力学”或简称“CFD”)已成为流体力学的一个特殊学科。
Real flows are described by partial differential equations which cannot be solved analytically in the general case. By dividing a complex flow domain into a multitude of small cells, these equations can be solved in anapproximate mannerby numerical methods. Because of their wide range of application, numerical flow calculations (“computational fluid dynamics” or “CFD” for short) have become a special discipline of fluid dynamics.
