STUDY ON HYDRODYNAMIC CHARACTERISTICS OF SWIRL BURNER BASED ON CFD

ABSTRACT
The numerical simulation method is mostly used to analyze the gas-solid two-phase hydrodynamics of swirl burner, ignoring the simulation of boundary conditions of swirl burner, resulting in poor simulation effect. To solve this problem, a CFD based study on the hydrodynamic characteristics of swirl burner is proposed. The physical model of swirl burner is constructed by using FLUENT software. The particle concentration of the burner is calculated, and the Lagrange motion function of gas-solid two-phase flow is established to obtain the boundary conditions of the swirling burner and simulate the gas-solid two-phase flow. The motion equation of swirl burner is constructed, the dynamic characteristics are analyzed, and the dynamic equation is derived. The experimental results show that the swirl burner has less response and better performance under the impact of rolling direction.
