Description

Various sources and mechanisms for bubble formation in superheated liquids are discussed. Bubble chambers can be filled with a great variety of liquids, such as e.g. the cryogenic liquids hydrogen, deuterium, neon, neon/hydrogen mixtures, argon, nitrogen, argon/nitrogen mixtures, or the warm liquids propane and various Freon like Freon-13B1. The superheated state is normally achieved by a rapid movement of an expansion piston or membrane, but can also be produced by standing ultrasonic waves, shock waves, or putting liquids under tension. Bubble formation can be initiated by ionizing particles, by intense (laser) light, or on rough surfaces. The creation of embryonic bubbles is not completely understood, but the macroscopic growth and condensation can be calculated, allowing to estimate the dynamic heat load

Abstract (French)

Plusieurs sources et mecanismes pour la creation de bulles dans les liquides surchauffes sont discutes. Les chambres a bulles peuvent etre remplies avec une grande variete de liquides, par exemple les liquides cryogeniques hydrogene, deuterium, neon, argon et azote, des melanges neon/hydrogene et argon/azote, ou les liquides chauds propane et divers Freons comme le Freon-13B1. L'etat surchauffe est generalement obtenu par un mouvement rapide d'un piston ou d'une membrane, mais il peut aussi etre produit par des ondes ultrasoniques, de choc, ou en mettant les liquides sous tension. La formation des bulles peut etre initiee par les particules ionisantes, la lumiere (laser) intense ou sur les surfaces rugueuses. La creation de bulles embryonnaires n'est pas completement connue, mais la croissance macroscopique et la condensation peuvent etre calculees, permettant l'estimation de la charge de chaleur dynamique
