Abstract

This Brief Report presents experimental and computational results on bubble formation in microfluidic devices. Bubbles are generated at the right-angle intersection of four identical square microchannels. When the pressure gradient generated by the liquid flow dominates the pressure gradient generated by gas flow, the length of the produced confined bubbles follows a law based on the channel size and fluid volume fraction. This bubble production technique was used to produce monodisperse aqueous foam in two-dimensional and three-dimensional microchannels.
