Summary
Doctoral dissertation in thermal and energy engineering from INSA in Lyon, France. It concerns the thermohydraulic study of a two-phase solid-liquid mixture, constituted by a suspension of fine ice particles in an aqueous solution, used as a secondary refrigerant in an indirect cooling loop. The thermophysical properties of the two-phase mixture and those of the residual solution are calculated from properties of an ideal mixture of pure compounds corrected by a function of excess, and prolonged in the two-phase domain with empirical correlations. A computer program has been developed in order to calculate these properties. A local three-dimensional model of flow and heat transfer based on equations of balance has been developed by using a computational fluid dynamics code (PHOENICS). While the results for a single-phase fluid are validated by the experiment, on the other hand those obtained for ice slurry give some results that are too far removed from the reality.
