13. Sensitivity computations using first and second orders perturbative methods for the advection-diffusion-reaction model of pollutant transport
This work aims to apply the disturbance theory to accomplish sensitivity computations in problems of pollutant transported in liquid media modeled through the advection-diffusion-reaction equation. The numerical solution of the differential equation that describes the behavior of the system was found via the SUPG ("Streamline Unwinding Petrov Galerkin") fini

14. NUMERICAL MODEL FOR A SIMULATION OF VISCOELASTIC FLUIDS VIA FINITE ELEMENTS / UM MODELO NUMÉRICO PARA A SIMULAÇÃO DO ESCOAMENTO DE FLUIDOS VISCOELÁSTICOS VIA ELEMENTOS FINITOS
A new numerical scheme has been introduced for viscoelastic fluid flows. First, it was studied the viscoelastic behavior with particular emphasis on equations in wich the extra stress tensor is not explicity dependent of the velocity field. Two of the most difficult to solve constitutive models have been considered, the Maxwell-B and Oldroyd-B. The numerical
