1. Locally Perturbative Multiscale Methods for Ionic Solute Transport in Clayly Soils / Modelos Multi-escala Localmente Perturbativos para o Transporte de Solutos Iônicos em Meios Porosos Argilosos
Este trabalho objetiva o desenvolvimento de modelos computacionais capazes de construir simulações numéricas mais realistas e menos custosas computacionalmente para o problema de descontaminação de solos argilosos por técnicas de eletrocinética. Resultados inovadores são obtidos aprimorando-se os modelos multi-escala desenvolvidos anteriormente por L

2. Boundary element method formulation for reinforced porous material / Formulação do método dos elementos de contorno para materiais porosos reforçados
In this work a nonlinear formulation of the boundary element method (BEM) is proposed to deal with saturated and unsaturated poro-elasto-plastic 2D reinforced domains. To model reinforced porous domains a BEM/FEM (Finite Element Method) modified coupling technique is employed. The coupling is made by using the least square method to regularize the displaceme

3. A COUPLED MODEL FOR TWO-PHASE FLOW THROUGH ELASTOPLASTIC POROUS MEDIA / UM MODELO ACOPLADO PARA FLUXO BIFÁSICO EM MEIOS POROSOS ELASTOPLÁSTICOS
This dissertation studies a coupled flow and deformation model for saturated and non-saturated soils, based on Biot`s theory but taking into account the nonlinear material behavior of soil. In the non-saturated condition the fluid flow can be considered either as a two-phase or an one-phase problem. In the two-phase case, the model calculates the pressure of

4. Efeitos da corrente eletrica continua na recuperação de petroleo
Many patents have been published about the effect of applying electrical potentials in order to enhance oil recovery. These investigations emphasize only heating effects that causes, in consequence, oil viscosity reduction. However, there are indications of the influence of other effects. The aim of this work was to investigate the effects of applying a dire
