Abstract
A method of removing a coating from a substrate comprises positioning a nozzle of an apparatus such that a longitudinal axis of a distal end of the nozzle is inclined at an angle θ with a coated surface of the substrate. The nozzle including an inner conduit having an orifice and an outer conduit coaxially arranged about the inner conduit and defining an annular opening between the inner and outer conduits. Directing a liquid stream through the orifice toward the coated surface and directing a gas flow through the annular opening such that the gas flow surrounds the liquid stream, and impinging the liquid stream on the coated surface.
