  • To develop a kind of high velocity combustion spraying gun which uses aviation kerosene for fuel, an efficient atomization nozzle is needed to be developed. A double air-flow assisted atomizing nozzle was put forward in the present study. The air flow field was analyzed by using computational fluid dynamics simulation method, including investigating the effect of the primary/second gas outlet area ratio on the air flow filed distribution. The results show that with the cone angle increases, the spraying airflow increases correspondingly, while the airflow maximum speed decreases. Combining the effect of the cone angle and airflow speed, it is optimized that the range of the primary/second gas outlet area ratio is 1.01~1.34. Then a nozzle with primary/second gas outlet area ratio of 1.01 was machined and assembled on a high velocity combustion spraying gun, the atomization perform of the nozzle was investigated by using a high speed camera system. It was found that the experimental atomization profile and cone angle obtained from the camera is consistent with the simulation result.
