本文的范围是给出一个比较评估的几个竞争有限差分格式解决一维对流反应问题。数值结果表明，与传统的一阶或二阶差分格式相比，通量校正输运（FCT）、守恒律单调上游格式（MUSCL）和加权基本无振荡（韦诺）格式等高分辨率格式能有效地跟踪陡峭的运动锋，并且对于网格点数较少的情况是必不可少的. Superbee通量校正器被认为是最合适的模拟反应堆模型的尖锐的前。(C)2004爱思唯尔有限公司保留所有权利。
The scope of this paper is to give a comparative evaluation of several competitive finite difference schemes developed to solve a one-dimensional convection-reaction problem. Numerical results show that compared with traditional first- or second-order difference schemes, the high-resolution techniques such as flux-corrected transport (FCT), the monotone upstream scheme for conservation laws (MUSCL) and weighted essentially non-oscillatory (WENO) schemes are efficient to track steep moving fronts and are essential for cases which use small numbers of grid points. The Superbee flux corrector is found to be the most appropriate for simulating the sharp fronts of the reactor model. (C) 2004 Elsevier Ltd. All rights reserved.
