Mixing of a Solute in a Micropolar Blood Flow Model Through a Capillary Tube with an Absorptive Wall

This study dives into the secrets of how solutes navigate in the dynamic flow of blood. Here, we investigate the process by which solute mixes with blood in capillaries in a time-independent flow with a first-order absorption parameter at the tube wall. The micropolar fluid model is considered to investigate the dispersion mechanism of the solute. To analyze the transport process, a generalized dispersion model is utilized. At large times, different transport coefficients are asymptotically evaluated. The dependences of the exchange, convection, and dispersion coefficients are assessed with respect to the wall absorption parameter. Variations of both axial fluid velocity and micro-rotational velocity of blood are discussed for different values of the micropolar parameter and coupling number. For different values of these parameters, it is observed that there is a significant change in the convection and dispersion coefficients concerning the absorption parameter. This work may have relevance in comprehending the mechanism of drug dispersion within the blood flow in capillaries.
