Résumé

In this study, parameters affecting the heat transfer characteristics of ice slurry were investigated experimentally. The initial concentration of the ethanol solution from which the ice slurry was produced was varied as experimental parameter. Moreover, the heat flux at the test tube surface was varied as the experimental parameters, and the heat transfer coefficients measured. The effect of initial ethanol solution concentration and heating conditions on the heat transfer characteristics was not significant, and the Nusselt number can be expressed as a function of apparent Reynolds number, ice packing factor and ratio of average ice particle diameter to test tube diameter.
