摘要
KT格式是Kurganov和Tadmor于2000年提出的一类用来求解双曲守恒律的高精度中心格式.本文利用KT格式分别求解一维、二维激波管模型问题,通过与其他几种经典格式的计算结果进行比较,发现KT格式在间断处展现出更高的精度.本文结果很好地验证了KT格式理论.
KT scheme is a high-resolution central scheme proposed by Kurganov and Tadmor in 2000.In this paper,KT scheme is applied to numerical simulations of 1-dimensional and 2-dimensional shock tube problems.It is found that KT scheme works better than others as regards the resolution of the waves appearing in the solutions.The results illustrate the theoretical support of KT scheme.
