A sequential solution procedure where the component flow is solved explicitly, gives severe restrictions on the time step given by the CFL condition. In this paper an implicit solution procedure is given and results from numerical tests are presented. The results are compared with the explicit solutions. As expected the implicit algorithm allows for substantially larger time steps.

In this article we present an alternative implicit molar mass formulation technique using binary mixture thermodynamics.

The resulting small spatial scales severely restrict the time steps if the mass transport equations are solved explicitly. Thus, an implicit formulation is derived where the Jacobian terms are analytical expressions based on binary mixture thermodynamics. We will present details of the implementation of this method in the LGR framework using Newton-GMRES and a multigrid-like, two-level iterative solver.

It is shown that for a nonlinearity of f and arbitrary growth and sign, which depends on the time variable and parameter, the initial value problem for the linear wave equation has a unique solution in a Colombeau subalgebra of bounded type. The proof is based on a fixed point theorem in an ultrametric topology on a closed subspace of these subalgebras. The results presented generalize and unify several existing results in the literature.

Under certain assumptions about the second member we showed that the generalized solution is an asmptotically almost automorphic in the sense of genaralized functions.
