摘要:
基于多重坐标系的静、动网格法和气-液-固三相流等技术建模，采用VOF（Volume of Fluid）和DPM（Discrete Phase Model）模型捕捉瞬态流场下的自由液面和脱硫剂分散的空间分布规律。数值模拟与水模实验得到的漩涡深度及高度具有一致性。结果表明：搅拌器转速和搅拌器浸入深度显著影响流场轴向速度和径向速度的分布，最大速度主要分布在搅拌器叶端；自由液面的漩涡深度随搅拌器转速的增加而增加，当漩涡深度延伸至搅拌器上端，受卷吸作用聚集在漩涡表面的颗粒开始进入流场内部，通过四股循环流动在罐内充分扩散。
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.
