Title: APPARATUS AND METHOD FOR GENERATING A MICROFOAM
Abstract:
An apparatus or method for generating a microfoam, the apparatus comprising a channel having an inlet (107, 110) and an outlet, a source of foamable liquid (101) and pressurised gas (102) arranged to feed into the inlet (107, 110), wherein the channel is comprised of an spatially oscillating flow channel (106) to provide an oscillating flow direction, the spatially oscillating flow channel (106) oscillating about a bulk flow direction, the spatially oscillating flow channel (106) providing a sequence of planar cross-sections perpendicular to the flow direction, with a sub-sequence of planar cross-sections that are perpendicular to the bulk flow direction in the plane (46) in question, the sub sequence comprising at least one plane (46) that does not overlap with at least one other plane (46) in the sub sequence.
