Computational Fluid Dynamics (CFD) has been applied extensively to great
benefit in the food processing sector. Its numerous applications
include: predicting the gas flow pattern and particle histories, such as
temperature, velocity, residence time, and impact position during spray
drying; modeling of ovens to provide information about temperature and
airflow pattern throughout the baking chamber to enhance heat transfer
and in turn final product quality; designing hybrid heating ovens, such
as microwave-infrared, infrared-electrical or microwave-electrical ovens
for rapid baking; model the dynamics of gastrointestinal contents during
digestion based on the motor response of the GI tract and the
physicochemical properties of luminal contents; retort processing of
canned solid and liquid foods for understanding and optimization of the
heat transfer processes. This Brief will recapitulate the various
applications of CFD modeling, discuss the recent developments in this
field, and identify the strengths and weaknesses of CFD when applied in
the food industry.
