Etude numérique et paramétrique de la combustion de particules d'aluminium

Abstract: Dans le but de prendre en compte la reactivite des particules d'aluminium issues de la combustion des pains de prop ergo1 solide qui sont places dans les lanceurs spatiaux, plusieurs modeles numeriques ont ete eprouves. Notre choix s'est rapidement porte sur le modele de Law puisqu'il permet de transiter continfiment d'une goutte d'aluminium a une goutte d'oxyde et de connaitre la taille du residu en fin de combustion ceci pouvant expliquer les depdts importants observes dans les moteurs fusee. En vue d'y etud… Show more

“…Most of the theoretical and experimental works on aluminum combustion available in the literature [3][4][5] deal with the combustion of metallic aluminum. While some thermodynamic data provided in those studies are also relevant for the reaction of isolated Al atoms with oxygen, there are some important differences between these two processes that render most of the conclusions made regarding the combustion of solid Al inapplicable to the present study.…”

“…[3][4][5][7][8][9][10][11][12][13][14][15][16] Most of these works focus on the electronic structure and properties of Al oxides and not on the reaction mechanisms leading to their formation. An exception is the theoretical study by Marshall et al,4 that provides some information about the thermochemistry and kinetics of the AlϩO 2 reaction.…”

“…More details about this complete model can be found in [24,25]. The particles phase (dispersed phase) as well as the gaseous phase are described by a set of partial differential equations representing the mass, momentum and energy conservation laws.…”

“…The mass transfer within the dispersed phase is modeled through the termω p,i whileΓ p−g,i represent the mass transfer between the gas and the particles due to the aluminum combustion. The model we use for the aluminum combustion is a development of the Law's model (1973) that was presented in [24,25].…”
