Heat stream in electroosmotic bio-fluid flow in straight microchannel via peristalsis

Abstract

Current study investigates the heat characteristics of electroosmotic phenomenon in bio fluid through a peristaltic wavy microchannel. To analyze the heat transfer, viscous dissipation is well-thought-out. The transport model includes of continuity, momentum, heat and electric potential equations with suitable boundary conditions. Debye Hückel linearization approximation is considered. Analytical solution of subsequent non-linear problem is presented to evaluate the variation in velocity, pressure gradient, pressure rise and temperature through the perturbation technique. We validate the approximate analytical solutions by comparing those with results from numerical analysis. Shear stresses and Nusselt number are calculated indeed. Presented graphical results explore the impact of the factors affecting the physical problem. Eyring fluid parameter expressively affects all the transport characteristics.Pressure gradient is more for Eyring fluid parameter and Helmholtz-Smoluchowski velocity and declines for averaged time flow rate and electroosmotic parameter. Shear stress strongly depends on Eyring-Powell fluid parameter A, electroosmotic parameter and Helmholtz-Smoluchowski velocity. The results reported provides a good insight into biological systems in biomedical engineering.
