On the basis of computational fluid dynamics (CFD), adopting limited volume method, the external flow field of a car body is simulated.
以计算流体力学(CFD)为基础，采用有限容积法模拟计算了轿车车身的外部流场。

A small volume of fluid, often of a higher density than the main body of fluid, within the circulating or production-fluid system that influences the flow or production characteristics of the well.
The justification for treating a fluid as a continuum. depends on the physical dimensions of the body immersed in the fluid and on the number of molecules in a given volume.
