Volume-averaged macroscopic equation for fluid flow in moving porous media

, 2014
Darcy's law and the Brinkman equation are two main models used for creeping fluid flows inside moving permeable particles. For these two models, the time derivative and the nonlinear convective terms of fluid velocity are neglected in the momentum ...
