equation 弓I言 在岩土工程界,饱和一非饱和渗流问题一直是 研究的热点问题.当前在考虑饱和一非饱和渗流 时,主要是解决岩土体中水的饱和度与空隙压 力尸(在岩土工程中一般指负水头)以及相对渗透 率与w的函数关系,即Sw=Sw),Krw=Krw(P) 【l .不过总的来说大家探讨的基本上都是相对渗 ...

The Buckley–Leverett partial differential equation has long been used to model two-phase flow in porous media. In recent years, the PDE has been modified to include a rate-dependent capillary pressure constitutive equation, known as dynamic capillary pressure. Previous traveling wave analysis of ...
