Test de la validité de la théorie de la modélisation à l'échelle pour le développement d'un modèle physique à l'échelle d'un conteneur frigorifique. 

Testing the validity of scale modelling theory in order to develop a physical scale model of a refrigerated container.

Résumé

Cold air is used to maintain fresh produce quality in refrigerated containers (RCs). Using a physical scale model (PSM) to create similar physical arrangements could enhance understanding of airflow patterns in RCs, without the prohibitive costs of researching on a full scale. However, similarity in the hydro/aerodynamic conditions within the RC is required. As a step towards a PSM of a RC, this work validates whether a smaller PSM of a pallet in a refrigerated space mirrors the performance of a larger PSM. The experimental conditions of the two models were scaled both by dimension and Reynolds number (Re). The smaller PSM successfully predicted the flow characteristics of the larger PSM. The mean absolute percentage difference between Re measured in both models ranged from 3.0 – 29.6%. In the future, we will evaluate the temperature control performance for pallets within a RC using a PSM.
