This work intends to provide numerical methods to solve the Stokes problem in a complex geometry for nonhomogeneous fluids. This model describes highly viscous flows, incompressible, whose viscosity is not uniform, depending on a certain agent concentration. From a mathematical point of vue, it is an elliptic problem coupled to a convection-diffusion equation, generating a non linear dynamics. The computational algorithm is based on an hybrid grid-particles discretization. A fractional-steps algorithm enable to separate the computation of the different phenomena involved, to take advantage of both these discretizations: Lagrangian methods are adapted to solve convection operators and Eulerian methods are used for diffusion. A penalization m...
