【摘要】 将Ｈａｙａｓｅ等的ＱＵＩＣＫ差分格式推广到非均分网格，给出了其差分计算公式，并进一步改进了边界差分格式。对方腔的自然对流换热问题计算表明，所给出差分格式的计算结果与已有文献一致，并且能够预测出所计算问题在低Ｐｒａｎｄｔｌ数时的物理振荡。更多还原

【Abstract】 This article developes Hayases’ work,adopts the QUICK sheme for a non-uniform staggered grid system,deals with boundary control volume in a different but simple way.For natural convection of Low-Prandtl Number fluid,QUICK scheme gave oscillatory convection,which is equal to the results by Tagawa and Ozoe using Utopia scheme.更多还原
