Study of eddy-initiated cavitation; cavitation in a venturi: analogy between water and sodium
Description
The test facilities and experimental research techniques are described: sodium loop, water loop, visualization of cavitation in water behind openings, cavitation detection. A theoretical study is then devoted to cavitation through separate bubbles, with special emphasis on flow in a venturi of gradually changing profile, and the relative motion of a cavitation bubble; a coherent model of equations describing the evolution of an isolated spherical bubble is given. A theoretical study of eddy-initiated cavitation is also presented. Finally the results of cavitation experiments carried out on the venturi line are given for sodium (at 5500, 4500, 2500) and water (at 160, 370, 570 and 700C)

On decrit les moyens d'essais et les techniques d'etude experimentale: boucle a sodium, boucle a eau, visualisation de la cavitation en eau derriere les orifices, detection de la cavitation. On presente ensuite une etude theorique de la cavitation par bulles isolees, et en particulier de l'ecoulement dans un venturi lentement evolutif, et du mouvement relatif d'une bulle de cavitation; on donne un modele coherent d'equations decrivant l'evolution d'une bulle spherique isolee. On presente egalement une etude theorique de la cavitation initiee par des tourbillons. On donne enfin les resultats des experiences de cavitation, realisees sur la veine venturi, dans le cas du sodium (a 5500, 4500, 3500 et 2500C) et de l'eau (a 160, 370, 570 et 700C)Files
