Pressure waves in bubble, two-component, two-phase flows. Theoretical approach
Description
Common methods of modelling pressure waves (global or acoustic) and their inadequacy are described. A model is proposed, based on a stochastic treatment of the gaseous phase. Different mechanisms which affect pressure wave propagation are analysed. The importance of interfacial momentum and heat transfer is confirmed

On montre comment les ondes de pression sont decrites par les approches habituelles (globale ou acoustique). On souligne les insuffisances de ces approches. On propose un modele permettant la description de ces ondes. La modelisation est effectuee a partir du traitement stochastique de la phase gazeuse. Les differents mecanismes conditionnant la propagation sont analyses dans le domaine lineaire. L'etude confirme que les phenomenes les plus importants sont les transferts interfaciaux de quantite de mouvement et de chaleurFiles
