Numerical Simulation of Swirling Burner in Cold State

摘要

The computer numerical simulation of swirling burner in cold state was taken in this paper. The swirling intensity and the expansion cone angle of the secondary air were the main simulation content. The outlet flow field and form of the combustor were got through the simulation, and the comparison of the airflow diffusion angle and the return flow zone were analyzed, and then the guidance suggestions on the design modification and operation adjustment of the existing swirl burner were proposed.
