摘要: Abstract This work investigates how simultaneous CO 2 bubbles desorb from water and n-heptane when these liquids become supersaturated with dissolved . Supersaturation is imposed locally by a miniature heater so grow at adjacent sites across the heater. To suppress buoyancy, experiments are performed low gravity conditions. The number of nucleation time delay depend on liquid properties heating power. Simultaneous do not exactly same rate calculations show that this corresponds to slightly different bubble temperatures. Moreover, they exhibit smaller growth rates than single similar conditions, an indication compete for As expand into surrounding cold liquid, heater's temperature decreases in fashion implying inception Marangoni convection. detach due g-jitters but following ways two liquids. However, always together sizes do. A triggered destabilization contact lines deemed responsible this.
