Abstract
A method for cleaning an internal surface of a narrow diameter channel includes steps of: flowing a liquid cleaning medium and a gas through the narrow diameter channel under a flow regime that creates surface flow entities in contact with and sliding along the internal surface of the narrow diameter channel, the surface flow entities having three-phase contact lines and associated menisci, the surface flow entities detaching contaminants with which they come in contact from the internal surface of the narrow diameter internal surface of the narrow diameter channel; and rinsing the internal surface of the narrow diameter channel to remove residual liquid cleaning medium and detached contaminants from the channel.
