Abstract

A numerical simulation is conducted to study the effect of a turbulent airflow on heat transfer on cuboid food. The simulation is carried out with the Large Eddy Simulation approach. Periodic boundary conditions are implemented to represent a drying chamber as a single isolated zone where the phenomenon is conserved. Conjugate modelling is performed by coupling air-food phases by boundary conditions of continuity at the food interface. Numerical code is validated with empirical correlations of Nusselt number. Results show that low stream wise separations (0.25) present the best and worst heat transfer. Therefore, the best heat transfer on the cuboid food is found at span wise distances higher than 0.5and stream wise separations higher than 0.25. These separations are recommended to have a reasonable food drying control.
