一种求解 KdV-Burgers 方程的迎风超紧致差分格式
An upwind super compact difference scheme for KdV-Burgers equation
摘要
Abstract
In this paper , an upwind super compact difference scheme (USCD ) is proposed . The numerical characteristics of USCD are analyzed by using Fourier analysis , and compared with other upwind difference schemes and upwind compact difference schemes . According to analysis , it is found that USCD has better resolution and lower dissipation . Numerical solutions of the Burgers and KdV‐Burgers equations show that the USCD scheme has high‐order accuracy and is effective for long time evolution .关键词
