摘　　要：In this paper, the dispersion of a soluble matter in couple stress fluids flowing through pipes and channels is investigated by taking into account the effects of homogeneous chemical reaction. The analytical expressions of the relative concentration distribution C¯ and the effective diffusion coefficient D* are derived under Taylor's simplified assumptions, and the numerical computation is carried out. The effects of couple stress parameters α¯, η¯ and chemical reaction rate constant λ on those quantities above are discussed.In this paper, the dispersion of a soluble matter in couple stress fluids flowing through pipes and channels is investigated by taking into account the effects of homogeneous chemical reaction.
