Table 1. Analytical air infiltration models by natural convection through the door opening
Figure 1. 3D geometry of sliding door model.
Figure 2 shows the air temperature field inside the cold room in the yz plane for x = 2750 mm, corresponding  to  the  middle  of  the  door  opening  (see  Figure  2  a),  and  the  tracer  gas  flow  in  a  3D  perspective  of  the  computational domain,
Figure 3 shows the numerical predictions of air infiltration rate profile during the door opening/closing cycle  for different air temperatures outside the cold room
