摘要：
Numerical simulation on combustion flow field of one gas turbine combustor which burning C12H23 was studied in the paper. What did we adopt in the paper is PDF fast chemical reaction model, SIMPLEC algorithm, Pressure-swirl atomizer and DPM random walk track model. This paper analyzed the difference between cold and combustion flow field, and the flow field performance under different turbulent models. Based on the interaction between turbulence and particle, fuel atomization performance was researched in the paper. The result shows that Realizable k - epsilon turbulent model which introduces swirl flow modification is better than any other one in the simulation of intense swirling flow combustion field. The exit temperature uniformity and the performance of fuel atomization are extremely coincident with the experimental data.
