Bubble nucleation and growth in fluids

摘要: The nucleation and growth of CO2 bubbles in non-Newtonian Newtonian fluids that were initially supersaturated under different pressures are investigated the present work. Quantitative information by means two cameras reveals at an immobile site bubble grows rapidly followed a linear increase diameter with time. After reaching critical size, detaches from stagnant to rise liquids exponential temporary for both distance. A simple physical reasoning was proposed qualitatively explain these observed phenomena. Recently, rate flow fields around micro-bubble measured microdevice micro-Particle Image Velocimetry water. This microscale gives new insight into complex mechanism could help develop rigorous theoretical modelling numerical simulation such as Lattice Boltzmann approach.
