摘要
综述了国外一维跨临界流数值模拟的主要研究进展,概括介绍了跨临界流的两种处理方法———激波捕捉法和激波拟合法,并重点介绍了一种简便、高效、稳定的实用算法(删减对流加速度项法)。
This article reviewed the major research advance in numerical modeling of one - dimensional transcrifical flow. The most popular methods used in transcritical flow solution are generally described, including shock - fitting method and shock- capturing method. In addition, a simple, effective and stable method is emphatically introduced.
