The present paper reports development of a multiphase and multiscale volume averaging computational fluid dynamic model to simulate cooling slope slurry generation process. Novelty of the present work lies in the accurate estimation of effect of grain refiner, modifier addition on thermophysical and morphological properties of the generated semi solid slurry, which establishes potential of the present model to be implemented as a process control tool to develop engineering components using the cooling slope generated slurry. The three phases considered here are parent melt (primary phase), nearly spherical solid grains and air (secondary phases). In depth investigation is performed to understand the transport processes involved in the cooling slope slurry generation process and the findings obtained are volume fraction of constituent phases, evolution and growth of primary Al particles, viscosity distribution, temperature field, velocity field, macro and micro segregation etc. Accuracy of the present model is confirmed by performing real time experimental validation of the chosen process conditions.
