A CO2 nozzle expels liquid CO2 under pressure through an orifice therein for converting the liquid into CO2 snow. The CO2 nozzle is contained within an elongated mixing cavity within a body which is coupled to an exhaust nozzle for directing the CO2 snow toward the workpiece. The CO2 nozzle includes several wings for creating aerodynamic turbulence within the elongated mixing cavity for enhancing the coagulation of the CO2 snow into larger CO2 snow particles or CO2 snowflakes.
