Simulation of gases in fruit storage chambers with lattice Boltzman.

The benefit of controlled- and modified-atmospheres for extending the storage life of fruits is worldwide accepted. However, there are secondary effects such as the incidence of anaerobic respiration or the off-flavour occurrence which are not sufficiently known and thus controlled. The study approaches the knowledge of those secondary effects by developing a spatial temporal model gathering fluid flow phenomenon and physic and physiological processes. The lattice Boltzman model used as framework for mimicking the fluid flow shows to be a very flexible tool which reproduces complex macroscopic behaviours on a down up strategy.
