The authors consider finite difference and finite element approximations to the solution of the multiphase, multicomponent problems. They also consider the problem of efficient integration, by means of system integrators, of the resulting semidiscrete finite difference or finite element systems for a certain class of flows. Techniques which incorporate adaptive timestep control are utilized. In this way they are able to adaptively control the integration process for problems in which the system stiffness may vary markedly. Representative examples in one and two dimensions corresponding to an enhanced oil recovery process (micellar-polymer flooding) are computed. Numerical results obtained using finite difference and finite element methods are presented in the one-dimensional case. Some new ideas related to adaptive upwinding in the finite element computations are used to control oscillatory overshoot. Both streamline finite difference and general two-dimensional finite difference schemes are described and applied in flow simulations.
