Abstract
In order to determine the suitable combustion temperature suitable for ampoule bottle production, the nozzle and combustion field were numerically simulated and analysed by using ANSYS fluent software to change the inlet diameter and inclination angle of nozzle, respectively. The influence of inlet diameter and inclination angle on the central temperature of combustion flame was determined, and the reference was provided for the condition of ampoule bottle forming. The results show that the inlet diameter has a great influence on the central temperature of the combustion flame and can obtain a more favourable processing temperature range when the inlet diameter is smaller, and the change of the inclination angle has no significant effect on the central temperature of the combustion flame. When the inlet diameter is 0.6 mm and the inclination angle is 20 °, the highest processing temperature range can be obtained. This study can provide a reference for improving the production efficiency of ampoule bottles.
