The two-stage High Velocity Oxy-Fuel (HVOF) thermal spray gun developed by the authors has a mixing chamber between a combustion chamber and a supersonic nozzle followed by a straight barrel. The combustion gas is discharged into the mixing chamber, then the gas temperature is lowered in the chamber by injecting nitrogen gas at room temperature. The lowered gas temperature is beneficial from the view point of less oxidation of the spray particle. In this paper, the gas properties in the mixing chamber are calculated for a wide range of mass flow rates of nitrogen gas.
