Solution of the mixed formulation for generalized Forchheimer flows of isentropic gases
Thinh Kieu · Journal of Mathematical Physics · 2020
This paper focuses on the generalized Forchheimer flows of isentropic gas in a porous medium, described by a system of two nonlinear degenerate partial differential equations of first order. We prove the existence and uniqueness of the Dirichlet problem for the stationary problem. The technique of semi-discretization in time is used to prove the existence for the time-dependent problem.
