摘要
介绍了计算流体力学和常用求解方法的特点 ,对于定常流动 ,通过增加维数的方法把对象划归为同一性质的问题 ,避免了控制方程的不确定性给求解造成的困难。以有限体积法为例说明了偏微分方程组向代数方程组转化的方法 。
The significance of computational fluid dynamics (CFD), which includes parabolic, elliptic and hyperbolic problem, is introduced.Time march method is adopted to make governing equations of fluid field a uniform pattern to steady problem, thus preventing the solving from the pre judgment of the equation characteristics, which simplifies the solution approach.As an example, the fluid field in a blade passage of a gas turbine is solved by means of Finite Volume Method (FVM) to demonstrate the application of CFD.
