Résumé

Reducing the amount of air infiltration through the doorways of food storage rooms would improve temperature control and the overall economics of food storage. In the UK a joint government/industry supported LINK project has been set up to look at methods of reducing air infiltration. The project is combining direct experimental measurement with computational fluid dynamics (CFD) modelling. A CFD model of air movement through a doorway has been developed and verified against conventional and laser Doppler anemometry (LDA) measurements. The CFD model has been shown to be generally accurate, however, there are areas where the accuracy is less than perfect. For example the CFD model predicted the shape of the vertical profile accurately, although it under-predicted the maximum velocity by 0.1 m s-1 and it predicted the height at which the airflow changed direction to be 40 mm lower than was measured by the LDA.
