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。
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.
