摘要
考虑奇异摄动对流扩散方程组在Bakhvalov-Shishkin网格上的迎风差分策略.得出在改进的Shishkin网格上迎风差分方程组的解是关于小参数一致收敛于连续解的,且在L∞意义下是一阶收敛的.数值实验证实理论结果的正确性,并显示估计是稳健的.
A system of singularly perturbed convection-diffusion problems is considered. The problem is discretized by an upwind difference scheme on a BakhvalowShishkin mesh. A uniform first-order error estimate is given in a discrete L∞. norm. Numerical experiments support these theoretical results and indicate that the estimates are sharp.
