✦ Synopsis

We report here a study of the transport and tracer dispersion properties of uids in a model of fractured media. The tracer dispersion process was analyzed using Newtonian and non-Newtonian uids (polymeric solutions). Experiments were carried out in a Hele-Shaw cell using axial ow and dyes as tracers. We analyze the in uence of polymers presenting shear-thinning characteristics on the dispersion properties. It was found that the dispersion coe cient decreases when polymer concentration increases.

The influence of hydrodynamic dispersion on thermal convection in a vertical Hele-Shaw cell is studied theoretically. The supercritical, steady roll motion, the heat transport and the stability of the motion are investigated. The dispersion effects are found to be small, but qualitatively different

A generalized Hele-Shaw flow is derived and analysed in injection and compression moulding which contains non-isothermal and non-Newtonian rheological behaviour of the molten polymers as well as non-symmetric effects. The corresponding fixed domain formulations for the flow are investigated from a m
