Numerical study of entropy production and electroosmotic effects in a particulate-fluid suspension under peristaltic motion of Prandtl fluid

Particulate-fluid flow involving chemical reactions plays a crucial role in pharmaceutical manufacturing, catalytic converters, and combustion processes. This research focuses on the analysis of mass and thermal transfer, highlighting the influence of electroosmosis and magnetic forces on the flow of Prandtl fluid through a peristaltic porous micro-channel. In addition, the multiphase flow attitude, affected by chemical reactions, is extensively examined. The flow model is formulated by utilizing the lubrication theory estimation, integrating lengthy-wavelength and creeping flow approximation to simplify the considered problem. To further simplify the problem, Debye linearization is used, resulting in a set of two ordinary differential equations. The outcomes indicate that velocity drops with rising magnetic field, while it enhances with the Helmholtz-Smoluchowski velocity coefficient. Furthermore, thermal distribution increases with greater concentrations of solid fragments and greater magnetic field. These findings provide valuable insights into optimizing mass and thermal conveyance in peristaltic problems, with potential appliances spanning numerous industrial and biomedical areas.
