WebJul 20, 2024 · The nonlinear Brinkman-Forchheimer-Darcy equation is used to model some porous medium flow in chemical reactors of packed bed type. The results … WebThe equation of motion contains integrals involving spatial deviations of the pressure and velocity, the Brinkman correction, and other lower order terms. The analysis clearly indicates why the Brinkman correction should not be used to accommodate a no slip condition at an interface between a porous medium and a bounding solid surface.
