In this paper, we construct radially symmetric solutions of a nonlinear non-cooperative elliptic system derived from a model for flame balls with radiation losses. This model is based on a one step kinetic reaction and our system is obtained by approximating the standard Arrehnius law by an ignition nonlinearity, and by simplifying the term that mo...

The major objective of this work is to present a conceptual design of a refrigeration system in which clathrate hydrate slurry is used as a two-phase secondary fluid. The new circulation loop allow to form and to dissociate continuously, with a tank reactor and heat exchangers, CO2 hydrate slurries for secondary refrigeration applications. The pape...

Managers and scientists often seek to use fire to restore and maintain historic or natural species composition, stand structure, wildlife habitat, landscape pattern and ecological functioning. Successful use of under-burning in forests and woodlands requires integration of fi re behavior and fire effects knowledge into the planning, implementation,...
La température du produit dans un meuble frigorifique de vente est très variable et cela influe directement la qualité et la sécurité des aliments. Cette variabilité est due au type de meuble (vertical, horizontal), à la position de produit dans le meuble, aux fluctuations de température ambiante du magasin (nuit/jour, heure d'ouverture, saison, cl...
This study was carried out in order to gain a better insight into evaporation and condensation phenomena due to natural convection in a domestic refrigerator without a fan.A model refrigerator loaded with moist cylinders was studied initially. CFD simulations took into account air flow, heat transfer (convection, conduction and radiation) and mass ...
Le procédé de friture-séchage de bois implique une ébullition intense. La pression au c½ur du bois peut atteindre 250 kPa. Dans de telles conditions, le transport de vapeur d'eau par perméation est considéré comme le mode de transport de matière principal dans un modèle simplifié de transport de matière et d'énergie. Celui-ci a été développé en l'a...
