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.
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。
Then, based on that, the turbulent motional differential equation for a pipe is made out From that, the turbulent flow and displacement laws for non-Newtonian fluids in a pipe have also been studied.
在此基础上，导出了适用于圆管的运动微分方程序。据此研究了非牛顿流体圆管紊流流场及两种非牛顿流体在圆管中的顶替规律。
The twined coil insert can make the fluids perform complicated three-dimensions mixed flow and induce the occurrence of turbulent flow ahead of time.
绕花丝内插物可使流体在流动方向上做复杂的三维混合流动，提前诱发湍流发生。
