涡量是流体运动的一个基本物理量，旋涡是流体运动中常见的一种基本形态，又是湍流的一种基本结构，它在理论上和工程实践中占有相当重要的位置。本文在吴镇远（Ｊ．Ｃ．Ｗｕ）方法的基础上，提出了一种新的数值计算方法——涡量修正方法。对炉内速度场及涡量场进行了计算，其速度场的计算结果与实验基本符合，在网格划分基本相同的条件下与ＳＩＭＰＬＥ算法所得结果相比，涡量修正算法更接近于实验结果，为流场的数值模拟提供了一条新的途径。 Vorticity is a basic physical quantity of fluid movement. Vortex is a common basic form of fluid movement and a basic structure of turbulence. It occupies a very important position in theory and engineering practice. Based on the J.C.Wu method, a new method of numerical computation, vorticity correction, is proposed in this paper. The velocity field and vorticity field in the furnace are calculated. The calculation results of the velocity field are in good agreement with the experimental results. Compared with the SIMPLE algorithm, the vorticity correction algorithm is closer to the experimental result under the same meshing conditions , Which provides a new way for the numerical simulation of flow field.
