本文研究带非线性强迫项的Burguers方程初边值问题的有限差分方法.构造了一个两层线性化隐式差分格式.证明了差分格式解的存在唯一性、收敛性和稳定性.并给出了差分解在L∞模意义下的收敛阶数为O(h2+τ2).数值例子验证了理论分析结果.
A finite difference scheme for Burgers equation with nonlinear force is proposed and analyzed.The scheme constructed in this paper is a two-level and linearized scheme.The order of accuracy is second-order in both time and space.It is shown that the difference scheme is uniquely solvable and convergent and stable in L∞ norm.Some numerical experiments are conducted to illustrate the theoretical results of the presented method.
