摘要:
采用Fluent软件对以Martin Thew液-液旋流器为基础的不同圆柱段长度模型进行了数值模拟,对比分析了分离效率、压力降、速度分布及流场,研究了圆柱段长度对旋流器的分离性能的影响. 结果表明:随着圆柱段长度的减少,分离效率呈线性增长,但当圆柱段长度趋近于0时,分离效率反而下降;底流口和溢流口的压力降随着圆柱段长度的减少而增大;随着圆柱段长度的减少,大锥段和小锥段处的切向速度和轴向速度逐渐增大,循环流区域逐渐减小;当无圆柱段时,循环流区域完全消失.
Abstract:
The Fluent software was adopted to simulate the models of different lengths of the cylinder section which were designed based on the Martin Thew's hydrocyclone. The comparative study of the separation efficiency, pressure drop, velocity distribution and flow field in hydrocyclones was carried out to research the influence of the cylinder section length on the separation performance of hydrocyclone. The results show that the separation efficiency increases linearly as the length of the cylindrical section reduces, but the separation efficiency reduces when the length of the cylindrical approaches to zero;the pressure drop of the bottom outflow and overflow increases with the length of the cylindrical section decreasing; the tangential velocity and the axial velocity in big and small conic sections increase gradually and the area of circulation flow decreases as the length of cylindrical section decreases, and the area of circulation flow disappears when no cylindrical section exists.
