Summary

This study concerns the use of mist flow whereby fine water droplets are injected into the air curtain to improve the performance of refrigerated display cabinets (RDCs). The deposition and evaporation of droplets on the surface of products partially compensate the radiative heat gained by the products by removing from it the amount of latent heat of the evaporated droplets. The experiments were carried out on an actual display cabinet. Numerical modelling was performed using Fluent computational fluid dynamics (CFD) software. In two-phase flow, an Euler-Lagrange approach was adopted to predict the transport of droplets by the air curtain and their spatial distribution on the product surface of the RDC. An original numerical procedure was built in the CFD model in order to compute the deposited droplets while taking into account the evaporative flux of droplets on the product surface. The two-phase flow model was used to analyse the performance of the mist cooling process in terms of surface temperature decrease and the homogeneity of droplet deposition on the product surface of the RDC as a function of inlet droplet injection configurations.
