Semi-rigid aluminum containers are being used widel
y in food industries. They have
wrinkle shaped walls for strengthening their physic
al structure. The objective of this
study was to assess the effect of wrinkled parts on
the heat transfer and temperature
distribution of the containers by Computational Flu
id Dynamics (CFD) analysis.
Therefore, a precise designed geometry of the wrink
led walls container was compared to
a straight one. The analysis was carried out based
on the physical properties of a carrot-
orange soup. The velocity vectors showed a strong c
irculation towards the core. The
Slowest Heating Zone (SHZ) locations were the same
for wrinkled and simplified
containers. Average temperature of the symmetric pl
ane and the coldest point of SHZ
showed less than 1% difference. The lethality impos
ed to the SHZ in the wrinkled wall
container was about 0.4% more than the straight one
. The simulation results revealed
that wrinkled walls do not play an important role i
n increasing heat transfer and as a
result, such geometries could be simplified while m
odeling.
