Transport of reactive species in oscillatory Couette-Poiseuille flows subject to homogeneous and heterogeneous reactions

作者：

Highlights：

• The study investigates the transport process by means of dispersion coefficient and cross-sectional distribution of solute.

• Heterogeneous (reversible and irreversible) and homogeneous (irreversible) reactions are considered.

• Three different kinds of flow pulsation have been considered.

• The source of flow pulsation can affect the dispersion process by violating the actual nature of chemical reactions.

• The cross-sectional distribution of solute strongly relies on the flow profiles rather than the rate of the reactions.
