Description
The exemple of the hydraulic jump is used to illustrate the notion that the two phenomena of, respectively, reaeration and air entrainment are not necessarily synonymous. In other words, the simple fact that a large quantity of air remains entrained in flowing water over a long distance due to a sufficiently high level of agitation does not, by itself, assure an efficient reaeration process. Rather, it is the thermodynamic equilibrium of the immersed air bubbles which constitutes the essential parameter of the diffusive mass transfer between the two phases involved
Abstract (French)
L'exemple du ressaut hydraulique est choisi pour illustrer l'idee que les phenomenes de reaeration et d'entrainement d'air ne sont pas obligatoirement synonymes. C'est-a-dire qu'une grande quantite d'air entraine sur une grande distance avec un niveau d'agitation suffisant n'assure pas pour autant un processus de reaeration efficace. C'est plutot l'equilibre thermodynamique des bulles d'air immergees qui constitue le parametre essentiel des echanges diffusifs entre les deux phases en presenceAdditional details
