摘要
以泰勒涡反应器的简化模型为研究主体,研究在不同泰勒数下环隙间流体的流动特性。通过改变反应器内筒转速的大小,借助Fluent和Tecplot等数值计算软件来系统研究环隙间流体的流场形态变化,阐述了环隙间泰勒涡胞经历了从生成、加强稳定、波动到最后破裂发展为湍流的过程,并对层流状态下的第一临界泰勒数和第二临界泰勒数展开了讨论。
Based on the simplified model of Taylor vortex reactor,the flow characteristics of fluid between annular gaps under different Taylor numbers are studied.By changing the speed of the inner cylinder of the reactor,the flow field morphology of the fluid between the annulus is studied systematically by means of numerical calculation software such as fluent and tepplot.It is explained that the Taylor vortex has experienced from generation,strengthening stability and fluctuation to.Finally the rupture develops into a turbulent process,and the first critical Taylor number and the second critical Taylor number in the laminar flow state are discussed.
