Abstract: In response to the high risk, substantial investment, and significant challenges associated with turbulent combustion experiments, a numerical simulation method for gas fuel turbulent non-premixed jet combustion was constructed based on the COMSOL Multiphysics platform. A simulation teaching software was developed that allows for adjustment of multiple parameters such as gas fuel composition, nozzle size, injection velocity, and chemical reaction rate. Numerical experiments were conducted on the jet combustion of two different gas fuels using this teaching software. The numerical experiment results were compared with the actual installation experimental data and the theoretical results of flame height prediction. Practical application demonstrates that the simulation teaching software effectively meets the requirements for experimental education. With the software, students can independently adjust experimental conditions and observation parameters to conduct multiple numerical experiments. Its visualization effects and interactive design effectively stimulate students’ interest in active exploration, thereby contributing to the enhancement of their autonomous learning ability, practical skills, and innovative capacity.
