摘    要:本文给出了QUICK格式在非均匀网格下近边界点与内点的统一形式,数值实验表明该格式提高了数值计算精度,但应用时需注意格式稳定性与网格Peclet数的关系;此外,通过数值实验,研究了用虚拟压缩方法计算低雷诺数传热问题时虚拟压缩因子的选取,并给出了一系列虚拟压缩因子的选择值。

关 键 词:QUICK格式  网格Peclet数  虚拟压缩因子

Abstract:The uniform expression of QUICK scheme in the inner flow field and near the boundary is introduced in this paper. Numerical computation is carried out and it is found that the QUICK scheme provides much accurate result, but the relationship between stability and mesh Pelect number is considered when it is used; In addition, a low Reynolds number heat transfer problem is simulated by artificial compressibility method to investigate the choice of artificial compressibility parameter and a series of parameters are given.
Keywords:QUICK scheme  mesh Peclet number  artificial compressibility parameter
