• A Lattice Boltzmann scheme is developed for the simulation of the heat and mass transfer during cooling of packed cut flowers. Using this problem as a case study, we investigate whether the Lattice Boltzmann scheme can be used as a generic tool in the design process of packages with agricultural products. The Lattice Boltzmann method has been chosen for its attractive simplicity and its appeal to physical intuition. The method maps the problem on a regular lattice, populated with lattice gas particles, which move across the lattice and collide with one another. Mathematical and numerical analysis have shown that our Lattice Boltzmann scheme is consistent with a convection–diffusion equation with heat and mass transfer, even up to high grid Peclet and Courant numbers. Comparison of the simulation results of the LB scheme with experimental data shows that the model applies quite well to cooling of packed cut flowers. Given the results of this study we conclude that the Lattice Boltzmann scheme is indeed suitable as a generic framework for the modelling of heat and mass transfer processes in packages of agricultural products.
