Convective heat and mass exchange at surfaces of horticultural products: A microscale CFD modelling approach

► Convective heat and mass exchange of horticultural products is modelled with CFD. ► Focus is on exchange processes at the microscale (i.e. lenticels, cracks, droplets). ► CFD validation indicates a good performance of the RANS SST k-ω turbulence model. ► Convective exchange is a function of coverage ratio, Reynolds number and source size. ► Microscale modelling is required for accurate convective exchange predictions.
