The rheological behaviour of a biphasic material is quite difficult to model because of the difficulties to represent the evolution of the space position of each solid particle in the solid matrix. The first part of this study consider an equivalent material by homogeneisation method. The main point of this first part was the representation of the rotation of the rheological mobile. The second part focus on the biphasic aspect of the problem. The aim of our study is to develop a model that is able to show the convection phenomenom in the liquid part, the influence of temperature, mobile geometry, rotation speed ... all parameters responsable of the quality of such mixing. This model was created and solved with COMSOL.
