1. Simulation of species concentration distribution in reactive flows with unsteady boundary conditions
Abstract The determination of species concentration profiles in reactive flows with variable inlets is a problem of practical interest to many fields such as in flow reactor transient operation and in cyclic degradable pollutants disposals in watercourses. In these cases, the inflow condition often consists of a time-dependent function, which may imply unste

2. Finite element simulation of viscous fingering in miscible displacements at high mobility-ratios
Numerical simulations of viscous fingering instabilities in miscible displacements at high mobility-ratios are presented. Anisotropic dispersion and monotonic viscosity profiles are considered. The coupled set of partial differential equations is approximated by the semi-discrete SUPG stabilized finite element formulation plus a discontinuity capturing techn

3. Stability of Semidiscrete Formulations For Advective-Diffusive-Reactive Transport Problems / Estabilidade temporal de formulações semi-discretas para problemas de transporte convectivo-difusivo-reativo
This work deals with the stability analysis of the fully discrete transport problem obtained using a stable finite element method in space and the generalized trapeizoidal family of methods in time. Depeding on the range of parameters the Galerkin and the Streamline Upwind Petrov-Galerkin Methods are introduced. We evaluate the accuracy and stability propert
