Bubble dynamics during degassing of liquids at microgravity conditions
Divinis, N.; Karapantsios, T. D.; de Bruijn, R.; Kostoglou, M.; Bontozoglou, V.; Legros, J. C. (2006)This work investigates the growth of bubbles generated in a liquid saturated with dissolved CO(2) when its temperature is rapidly and locally raised above the saturation value, still below the boiling point of the test ... -
Bubbles growing in supersaturated solutions at reduced gravity
Divinis, N.; Karapantsios, T. D.; Kostoglou, M.; Panoutsos, C. S.; Bontozoglou, V.; Michels, A. C.; Sneep, M. C.; De Bruijn, R.; Lotz, H. (2004)This work investigates bubbles growing in a liquid saturated with a dissolved gas when its temperature is locally raised above its saturation value, yet below boiling. Local supersaturation is realized by giving heat pulses ... -
Lateral motion and interaction of gas bubbles growing over spherical and plate heaters
Divinis, N.; Karapantsios, T. D.; De Bruijn, R.; Kostoglou, M.; Bontozoglou, V.; Legros, J. C. (2006)This work investigates the motion of CO2 bubbles emerging in n-heptane when a heat pulse given to a submerged heater creates local supersaturation. The ensuing slow diffusion-induced bubble expansion makes bubble motion ... -
Nucleation, growth and detachment of neighboring bubbles over miniature heaters
Karapantsios, T. D.; Kostoglou, M.; Divinis, N.; Bontozoglou, V. (2008)This work investigates how simultaneous CO2 bubbles desorb from water and n-heptane when these liquids become supersaturated with dissolved CO2. Supersaturation is imposed locally by a miniature heater so bubbles grow at ... -
Self-similar growth of a gas bubble induced by localized heating: the effect of temperature-dependent transport properties
Divinis, N.; Kostoglou, M.; Karapantsios, T. D.; Bontozoglou, V. (2005)A gas bubble growing in a saturated liquid under the action of an internal heat source is studied theoretically as a model problem for the growth of a bubble around a miniature spherical heater submerged in the liquid. In ...
