Measurement of concentration distributions for the dispersed-phase flow in a mixing reactor with the laser light scattering by particles

摘要: 研究了圆管反应器中四束侧向对撞射流与轴向流形成的混合流动.应用激光粒子散射成像测量了侧向分散相在混合流中的浓度场分布,得到了不同的浓度分布图形随侧向流与轴向流速比关系,揭示了内在有规律的独特的浓度分布结构.

Abstract: A tube reactor mixed by an axial continuous flow and four side jets as the dispersed flow is studied.The concentration distribution of the dispers~ed flow was measured by means of the laser light scattering.The different flow patterns revealed the special construction of concentration distributions in relation with the velocity ratio of side flow and axial flow.
