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.
