【摘要】 本文提出了求解定态对流扩散方程的修正Dennis格式。对模型问题的初步分析和数值计算表明在相当程度上克服了Dennis格式的异常不精确性质(Peclet数大时)。更多还原

【Abstract】 In this paper, A modified Dennis scheme for the steady-state convection-diffusion equation is proposed. Elementry analysis and numerical computation for model problem show that, the highly inaccurate behaviour of Dennis scheme is corrected by modified Dennis scheme.更多还原
