| 摘 要： | 为在中型机上实现对湍流运动的大涡模拟,采用Moin的基本模型,在数值计算中采用了诸如高斯滤波函数、速度压力交错网格、谱方法以及一种简单的压力计算的修正等方法和技巧,计算结果与Moin结果比较,表明在我国现有条件下也有可能进行大涡模拟方面的工作。

| Abstract: | The purpose of this paper is to realize the large eddy simulation (LES) of turbulence with a moderate computer. The Moin's model was used in the present paper. Some methods and techniques in the calculation were used, such as Gaussian filter function, stag-grid system of velocity and pressure, spectrum method and a simple revision method of pressure computation. The comparisons with Moin's results show that our results are reliable and man can also make LES in our present conditions in China. |
