摘要
考虑等温下在圆管层流的双极流体中溶质的弥散规律及其化学反应效应。利用Taylor简化假定,导出相对浓度分布(?)和等效扩散系数D*的解析式,并作了在双极应力M_(?)=0条件下的数值计算。分析了双极参数h_1/H_3,R/l和化学反应率参数β对上述量的影响。
The dispersion law of soluble matters in laminar flow of isothermal dipolarfluid through a circular tube and the effects of its chemical reaction are discussedin this paper. Analytical expressions are obtained for the relative concentrationdistribution (?) and the effective diffusion coefficient D* under Taylor's simplifiedassumptions, and numerical computations are performed for the case M_z=O. Ananalysis is also given for the effects of dipolar parameters h_1/h_3, R/l and chemi-cal reaction rate constant β on those quantities. Moreover, it is also shown thatthese formulas for dipolar fluid are closely related in form to the formulas formicropolar fluid in a circular tube.
