摘要
简要介绍了ＱＵＩＣＫ格式及其精度，推导了三维ＱＵＩＣＫ格式的系数及其假扩散系数，并将ＱＵＩＣＫ格式应用于大型Ｗ型火焰电站锅炉三维冷态炉内流场的数值计算，计算结果能反映炉内流动的基本特征．
Ih this paper, the QUICK scheme and its precision is concisely presented, the three-dimensional QUICK scheme coefficient and its false diffusion coefficient are derived, the QUICK scheme is applied to the numerical calculations of the three-dimensional cold-state flows in the large W-shape flame power boilers. the calculation resuit is able to show the basic characters of flows in the boiler.
