Bubble rise dynamics in a viscoplastic material
(2015)The axisymmetric dynamics of a bubble rising in a Bingham fluid under the action of buoyancy is studied. The Volume-of-Fluid (VOF) method is used to solve the equations of mass and momentum conservation, coupled to an ... -
Bubbles growing in supersaturated solutions at reduced gravity
(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 ... -
Effect of wall roughness on shear viscosity and diffusion in nanochannels
(2010)The effect of wall roughness on liquid argon shear viscosity and diffusion coefficient in nanochannels is studied by non-equilibrium molecular dynamics. Diffusion coefficient results are presented in terms of average values ... -
Nucleation, growth and detachment of neighboring bubbles over miniature heaters
(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
(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 ...
