该模型经实验验证，在非湍流区偏差不超过10%，在全湍流区偏差不超过19%。
The deviation between the model and experimental data is not more than 10% in turbulent flow zone and 19% in non-turbulent flow zone.
二流湍流模型假设湍流流场中的每一点为“湍流”和“非湍流”流体所交替占据，从而模拟了湍流的“间隙”现象。
It is assumed in the two-fluid model that the turbulent and non-turbulent fluids occupy the turbulent flow field intermittently and thus the "intermittency" phenomena of turbulence are simulated.
湍流是一种高度复杂的三维非稳态、带旋转的不规则流动。
Turbulence is an extraordinarily complex three-dimensional flow which is unsteady, inerratic and composed of eddies.
