摘要
三阶线性守恒型方程具有多个守恒律,本文对该方程设计了一种守恒型数值格式。该格式能满足方程的前两个守恒律。通过数值算例验证了格式有效性,数值结果表明,该格式在长时间的数值模拟中具有很好的稳定性和保结构性。
Based on the third-order linear conservation equation’s many conservation laws, this paper de-signed a conservation numerical scheme which can satisfy the first two conservation laws of the equation. The numerical examples show the scheme’s effectiveness and the good stability and structure preservation in long-term numerical simulation.
