Contribution numérique à l'étude hydrodynamique et thermique des écoulements turbulents induits par une turbine radiale en cuve agitéeNumerical contribution in studies of turbulent flow and heat transfer in a vessel agitated by radial turbine

The hydrodynamic and thermal behaviours induced by a six flat-bladed turbine, in a closed, unbaffled, batch stirred vessel are numerically predicted by means of Computational Fluid Dynamic (CFD) model. Heat transfer is applied on the jacketed wall of the stirred vessel. Solutions of the time-averaged Navier–Stokes and energy equations in conjunction with the standard k–ε turbulence model are developed using a control volume discretization method.
