Abstract The tetrafluoroethylene explosion model was established by Fluent software, and the tetrafluoroethylene explosion in a cylindrical reactor with diameter of 70 mm and height of 500 mm was numerically simulated. The changes of temperature and pressure in the reactor were analyzed, and the flame and pressure wave characteristics of the explosion field were revealed. The results show that within 20 ms after the ignition of tetrafluoroethylene, the pressure and temperature of the monitoring point in the reactor rise rapidly, and then the values rise gently with the maximum temperature of 2 000 K and the maximum pressure of 608.000 kPa. The simulation results are consistent with the experimental results in the literature, which can verify the reliability of the tetrafluoroethylene explosion model. The research results can provide technical support for predicting the consequences of fluorine chemical tetrafluoroethylene explosion.
