Abstract:
A theory for momentum transfer in chemically active microstructured media is proposed. This theory is based on the assumption of the existence of a continuous internal parameter, which is determined by the mean statistical structure of the medium and obeys the main principles of rheology and physical kinetics. Expressions for the stress-tensor components are obtained, which permit estimation and analysis of the influence of physico-mechanical properties of the medium and external factors on momentum-transfer characteristics. As an example, spatially uniform flows are considered (unsteady shear, oscillating, and elongation ones). The results can be used in studying flows with complex deformations).
