此外,与固体不同,流体在运动时内部各部分之间可以具有不同的速度,且难以保持固定的形状,因此描述流体运动时我们需要选择合适的模型。 流体微元(Fluid Element)和有限控制体(Control Volume) 在研究流体时,我们首先可以选取流体中一个流体微元,且这个流体微元满足连续介质假设,即: 宏观上足够小,小到这个流体微元可以...

The fundamental difference is that with finite difference methods, you solve the differential form of the equations (via Taylor series representation of the derivatives), and in finite volume methods you solve the integral form of the equations (via control volume approach). As Praveen said, the ...

The control volume method is also known as the finite volume method. The basic ideas and methods are: the calculation area is divided into a series of unoverlapping control volume, and each grid point is contained in a control volume, the differential equation to be solved for each control ...
