摘　　要：给出了贴体坐标的网格方程及其离散格式,贴体坐标的流场方程.采用贴体坐标和传统的直角坐标方法分别对包钢150 t LF炉模型进行了网格划分及模拟计算.对比两种方法算出的流场,可以得出贴体变换对处理复杂边界问题的优越性及对内部流场的影响.The body-fitted coordinates equation and discrete format,as well as body-fitted coordinates of the flow field equation were presented.Using body-fitted coordinates and the traditional Cartesian coordinates,the 150 t LF model of Baogang Group was meshed and simulated.By comparing the two kind of methods of the calculated flow field,the superiority and the internal flow field effect of using body-fitted method on complex boundary issues were obtained.
