- Abstract:
- In order to capture the free surface under transient flow field and get the spatial distribution of desulfurizer dispersion, the VOF（Volume of Fluid）model and DPM（Discrete Phase Model）model, as well as static and dynamic grids based on the multiple reference frame and gas - liquid- solid three phases flow modeling technology were used. The numerical simulations of free surface vortex depth and height were in good agreement with the water model experiments. Results showed that the rotational speed and stirrer immersed depth significantly affect the distribution axial velocity and radial velocity, and maximum speed mainly distributed in the blender blade tips. The vortex depth of free surface increased with the increase of stirring speed significantly, and when the vortex extended to the mixer upper, the indrawn desulfurizer flux from the bottom of vortex began to disperse into the internal flow field and diffuse completely through four circulation flow in the stirred vessel.
