Abstract
A device of the present invention for applying a cryogenic composition includes a machining tool or tool holder having a channel positioned therethrough and a capillary tube positioned within the channel. A dense cryogenic fluid is passed through the capillary tube while a diluent or propellant fluid is passed through the channel. The diluent or propellant fluid flows within the channel and about the capillary tube. Upon exiting the capillary tube, the dense fluid admixes with the diluent or propellant fluid to form a cryogenic composite fluid or spray. The cryogenic composite fluid or spray is selectively directed onto a substrate for cooling or lubrication purposes, or onto the machining tool for cooling purposes.
