AN EXACT SOLUTION TO THE NONLINEAR DIFFUSION CONVECTION EQUATION FOR 2-PHASE FLOW
A new exact solution to the nonlinear diffusion-convection equation ∂θ/∂t = ∂/∂x(D(θ)∂θ/∂x)-V(t) ∂f(θ)/∂x, for two-phase fluid flow in porous media is derived. The solution is sought for Dirichlet boundary conditions and a diffusivity of the form D(θ) = D0/(1-νθ)2. The functional form of the fractio...
