Modelling and numerical simulation of ice slurry storage tank

Abstract Ice slurries, composed of an aqueous solution and water ice crystals, are used in new environmentally friendly refrigeration systems in order to reduce the amount of refrigerant. The slurry storage tank is an equipment which is important to correctly design. A numerical model was proposed to predict the evolution of the ice stock and the available cooling power in function of the tank geometry and the operating conditions. It takes into account ice settling, fluid circulation, ice formation (in generator) and ice melting (in utilisation loop and because of heat losses) . It can be used to optimise the operating conditions and the geometrical parameters of the ice slurry storage tank.
