Bubble crystallization induction chemistry
WebBubble formation: (a) flow-focusing configuration and (b) T-configuration. (6.22) where μ is the viscosity of the liquid phase. The formation process does not depend on the surface tension. In a T-configuration, the two formation regimes are determined by the gap g between the bubble and the top channel wall.
