NUMERICAL SIMULATION AND EXPERIMENTAL RESEARCH OF MULTI-PIPE JET FIREBALL

ABSTRACT
This paper studies a self-designed high temperature fireball quasi-static simulation device to understand the temperature distribution of each substance inside the fireball under the multi-pipe injection technology. The changes in the physical field of the high temperature fireball are obtained through numerical simulation. The simulation model in this paper adopts the turbulent k-ε model, and simulates the material transfer process according to Fick's law. The commercial software COMSOL multiphysics is used to give and analyze the local characteristics of fluid-flow and heat transfer. The simulation device formed a high temperature fireball under the interaction of the three-way jet fire. The experimental data verified the accuracy of the simulation results, and the experimental results were in good agreement with the simulation results. This method of analyzing the actual temperature field through simulation can be used to provide a powerful verification scheme for the detection of complex multi-temperature fields in the future.
