This paper presented an industrial application of
CFD to an operational cold store for the long-term
storage of fruits and vegetables, in which the air¯ow
pattern was investigated. Flexibility has been built in the
CFD model with an additional model for the cooler
unit. With an average dierence of 26% between calcu-
lated and measured velocities, it becomes only possible
to have a qualitative insight into the air¯ow pattern for
dierent product stacks, dierent fan rotation speeds
and dierent room designs, without the need for addi-
tional experimental determination of boundary condi-
tions for the velocity. The main de®ciencies of the
air¯ow pattern, which cause quality losses in a venti-
lated space, can be investigated. However, the limited
accuracy of the present air¯ow calculations will not be
sucient to perform detailed calculations of product
quality evolution as aected by a cold air¯ow during
long-term storage.
