7.2 TWO-DIMENSIONAL FLOW THROUGH POROUS MEDIA (SEEPAGE FLOW)

Formulation presented in this section is focused on the two-dimensional fluid flow analysis. However, the same formulation is applicable straightforwardly to two-dimensional torsion and two-dimensional steady state heat flow (in the absence of convection). At steady state, the governing differential equation for these problems can be written as
