涡量修正法数值模拟及锅炉屏区流场研究

Numerical simulation of vorticity tuning method and research on the flow field in platen zone

推导了涡量修正法在二维常密度粘性流动中的积分表达式，并对驱动方腔内的定常粘流问题进行了数值检验，结果令人满意．同时应用这种新方法对锅炉屏区的二维等温流场进行了计算，计算结果较准确地预测了炉内屏区实际流动情况．

This paper has presented a deduction of a 2 D integral expression of the vorticity tuning method in solving the constant density viscous flow problems. The driven cavity flow is computed as an example and the result is satisfactory. This new method is also applied to the 2 D flow in the platen zone of the boiler.The computation successfully plays a role in the numerical prediction.
