Based on shallow-water approximations the governing equations for two dimensional two-phase gravity currents over a porous substrate and some appropriate bounda
The influence of the condensed structure of poly(styrene-co-acrylonitrile) (SAN) and traces of tetrahydrofuran (THF) that remained in titanyl phthalocyanine (Ti
A new kind of governing equations for water hammer based on the elastic column theory was proposed and adopted to analyse water hammer phenomenon in the pipe sy
