Sa. Vakulenko et Ia. Molotkov, THE INITIAL-STAGE IN THE EVOLUTION OF DISPLACEMENT FRONTS IN THE NONLINEAR FILTRATION PROBLEM, Journal of applied mathematics and mechanics, 61(1), 1997, pp. 103-109
A non-linear filtration model is considered. The initial stage in the
evolution of the displacement front is studied and the initial conditi
ons are found under which the front maintains a stable form for a long
time. Concentration and pressure profiles in a direction normal to th
e front are obtained. It is found that the concentration varies compar
atively rapidly here while the pressure varies extremely slowly. (C) 1
