Resumen:
Hydrofluidization (HF) is a method of chilling and
freezing of foods that pumps a refrigerating liquid upwards through orifices
into a vessel creating submerged jets and thus results in extremely high
surface transfer phenomena. The objective was to model the heat transfer and
turbulence intensity in a HF system with spheres through computational fluid
dynamics and a discrete element method. The HF system and the operative
variables were those used in a companion paper presented as Part I. The
independence of the mesh was checked. The heat transfer model was validated
using data from a previous study with static spheres. The results were in the
range of experimental data obtained in similar conditions. The model proposed
provides useful information about the relationship between the operative
variables and the heat transfer and turbulence levels in a HF system.
