Based on the principle of compressible fluid dynamics and thermodynamics and heat transfer, the basic equation and calculation formula for characterizing gas flow characteristics in tubular and casing cross-sectional spray guns under the combined action of friction and heat source were derived. The gas flow in the spray gun can reasonably determine the distribution of the inner wall temperature and gas stagnation temperature along the pipe length and the friction coefficient of the spray gun in the blowing process. The calculation formula of the gas flow in the spray gun under different flow regimes is given .
