摘要
本文在详细分析以往隐格式构造思想的基础上,提出了一种无近似因子分解、无矩阵运算、且计算量小的隐格式构造思想,并将该格式构造思想用于MacCormack显格式中去,得到的MC-LB格式通过算例分析,其在收敛性激波捕获能力及三维流动的稳定性方面均有较好表现。
The ided of making implicit numerical algorithm uithout block-bidiagonal system of equations and approximate factorization is developed on the basis of analysing some key implicit algorithms in this paper and some calculation exampes are given by using MC-LB scheme which put the above idea into the Mao Cormack explicit Scheme to show that the MC-LB scheme has abvious Superiority in aspects of convergence, accuracy of shock and the stability.
