Three-dimensional turbulence numerical simulation method was used, and the control equations are discrete by the finite volume method.

选用三维湍流数值模拟的方法，用有限体积法对控制方程进行离散。

Turbulence is an extraordinarily complex three-dimensional flow which is unsteady, inerratic and composed of eddies.

湍流是一种高度复杂的三维非稳态、带旋转的不规则流动。

At last, three-dimensional mathematical model of gas-particle two phase turbulence was established, and it was adopted to study the gas-particle two phase rectangular jet as well.

最后，在前面二维模拟的基础上，建立了三维气粒两相湍流流动数值模拟的数学模型，并用此模型对气粒两相气粒两相矩形射流进行数值研究。
