Paper presented at the 7th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Turkey, 19-21 July, 2010.
The mathematical modeling of liquid-solid flows is very complex because the solid particles distribution in the carrier liquid is heterogeneous or even when moving beds occurs. In this paper, a mathematical modelling and a numerical simulation of the flow behaviour of the paraffin slurry in a horizontal rectangular channel are presented . The pressure drop was presented and analyzed. The diffusion equation was solved, and the concentrations of suspended solid particles in the mixture have been given for some values of the mixture's average velocity.
