Application of Computational Fluid Dynamics (CFD) Simulations to Spray-Freezing Operations

Application of Computational Fluid Dynamics (CFD) Simulations to Spray-Freezing Operations

A 3D computational fluid dynamics (CFD) simulation for spray-freezing in a cold gas has been developed and used to identify design improvements. This model includes an approximate method to model the latent heat of fusion and is able to track particle trajectories. The simulation predictions agreed...
