摘要 将传统的GDQ方法与Lax-Wendroff型时间离散相结合,构造出一种时空同步离散的高精度守恒型差分方法.数值试验证明该方法能够很好的模拟激波、压缩波、稀疏波和接触间断等流场特性,并具有精度高、计算量小、形式简单、边界条件易于处理等优点. Combining traditional GDQ method with Lax-wendroff time discretization,a new high order conservational discretization GDQ scheme is constructed. It is simple and high efficiency and uses less memory. The numerical experiment verifies that it can simulate shock wave, compress wave and rarefaction wave well.
