摘要
在曲线坐标系下运用非交错网格的 SIMPLE方法对电站锅炉炉内的湍流流动进行了数值模拟 ,导出了任意三维曲线坐标系下椭圆型 N-S方程的通用形式 ,得到了较为满意的结果 ,较好地解决了锅炉数值模拟中存在的燃烧器喷嘴处伪扩散严重的问题 ,为求解复杂区域内的传热传质。
The value simulation of boiler furnace turbulence was carried out using non crossing network SIMPLE method under curve coordination system and the general form of the elliptic N S equation under abitrary 3 dimensional curve coordination was derived with satisfactory result, by which the serious question of psudao disperse at burner nozzle existed in the boiler values simulation is solved and a basis for solving problems concerning heat transfer medium, flow and combustion was established.
