Heat transfer and flow of a dense suspension between two cylinders

Concentrated suspensions, composed of solid particles and fluids, are used in many industrial applications. In this paper, we study the effects of temperature on the flow of a concentrated (dense) suspension between two long rotating cylinders. The viscosity of the suspension is assumed to depend on temperature and volume fraction of the solid particles. Based on these concepts, a generalized viscosity model is proposed and the model parameters are fitted with experimental data. The numerical results show good agreement with the available experimental measurements.
