Computational fluid dynamics (CFD) applications in spray drying of food products

The application of computational fluid dynamics (CFD) in the
area of spray drying of food ingredients is reviewed. The results
from previous studies have shown thatCFDcan be useful tool for
predicting the gas flow pattern and particle histories such as
temperature, velocity, residence time and impact position.
Moreover, CFD can also be used for investigating different
chamber design on drying behaviour of food materials as well
as scale-up studies. This paper provides the aireparticle interactions,
different turbulence models, reference frames, reaction
engineering model used for spray-drying applications along
with the particle histories and different spray chamber configurations.
The recent developments in this research area such as
drying kinetics model, dropletedroplet interactions, unsteady
state simulations and integration of population balance model
are discussed. In addition, the current limitations and future
scope for the potential research are also highlighted.
