摘要
研究在渠道层流的微极流体中溶质的弥散规律,考虑了化学反应效应.利用Taylor简化假定,导出相对浓度分布c和等效扩散系数D的解析式,并作数值计算,分析了微极参数λ,Τ和化学反应率参数β对上述量的影响.
This paper studies the dispersion law of soluble matters in a laminar flows of micropolar fluids through a channel and considers effects of chemical reactions. Expressions of the relative concentration distribution c and the effective diffusion coefficient D are derived under the Tayloy's simplification, and numerical computations are made. A discussion is given on the effects of micropolar parameters λ and T and the chemical reaction rate constant β on the quantities mentioned above.
