Modélisation numérique de l'entrée d'air et du schéma d'écoulement d'une pièce contenant un système à gaz avec une chambre à combustion ouverte.

Numerical modelling of air supply and air flow pattern of a room that contains a gas appliance with open combustion chamber.

Résumé

In the last decade, quite a few carbon-monoxide intoxications occurred in Hungary due to the inadequate operation of gas appliances with open combustion chamber, connected to chimneys. These cases emphasized the importance of faultless air supply of the appliances and the safe removal of the incipient flue gases. This problem gave reason for the modelling of air supply, temperature and velocity distributions in the space that contains the gas appliance. For the modelling of changes caused by the variations in the inside or outside ambient conditions, numerical modelling can be used. With the help of CFD, the phenomena can be studied in what is virtually a computational environment. CFD modelling gives results for the changes in the magnitude and direction of air velocity in the room and between the air inlet and the appliance, temperature distribution in the room and from the weather factors, the effect of wind on the operation of the air inlet.
