摘要
采用ＡＬＥ算法，选用与流动方向较一致的网格体系，对四角切向燃烧煤粉锅炉炉膛内冷态流场进行了模拟。此方法计算稳定、收敛性好，在数值计算中很大程度上消除了伪扩散的影响，模拟结果与前人实验值基本相符。
The cold flow field in the tangential firing boiler furnace is numerically studied by using ALE algorithm together with a grid system which is consistent with the flow direction in the furnace.The theoretically calculated results are in good agreement with the experimental ones and also show that the used calculating method has many advantages,such as,stability and convergence in iteration.Especially,the pseudo diffusion can be effectively reduced by using the used grid system.
