For an incompressible fluid in steady flow, the equation takes the following form. 对于不可压缩流体作稳恒流动的连续性方程有如下形式。
The weakly compressible fluid control equations and the large eddy simulation turbulence model are expounded. 摘要阐述了二维弱可压缩流体流动控制方程和大涡模拟湍流模型。
Besides, the authors find that fluid compressibility has little impact on the natural frequencies of structures in shallow water. 而流体的可压缩性对于浅水域结构固有频率影响不大。
