An investigation on flowing patterns of the airflow and its characteristics of heat and mass transfer in an island open display cabinet with goods

摘要

This paper presents a mathematical model that is based on the fundamental equations of conservation of mass and energy to describe the flow patterns of airflow and the process of its heat and mass transfer for a horizontal turbulent buoyant jet. The model was successfully tested for one island open display cabinet, and could be used to optimize the design and manufacturing display cabinets, for example the diameter of outlet grills and the dimensions of cabinets, for manufacturers, and predict the using performance, such as the heights and shapes of stacked goods with the heat transfer of the cooling air curtain, for supermarkets at where employ them.
