Utilisation de la modélisation par dynamique numérique des fluides pour la prévision des écoulements à travers les portes dans les chambres froides.

Using computational fluid dynamics modelling to predict airflow in and through the entrances of cold storage rooms.

Résumé

To optimize the safety and quality of the food within a cold store, it is important to maintain the store at its correct temperature. Measurements have shown a 3 °C variation in product average temperatures at different positions within a chilled store and during defrost air temperatures increased to 15 °C. It is difficult to predict temperature abuse within a cold store as the factors that can cause it are numerous and the size and configuration of cold stores vary greatly. The paper shows how CFD has been used to look at the effect of room configuration and infiltration through doorways on airflow and temperatures. CFD predictions have been found to agree well with practical measurements. They have been used to study the effects of changing the geometry of a cold store and using an air curtain on a cold store entrance.
