Electro-osmotic analysis of Williamson fluid model with viscous dissipation and enthalpy

The current approach aims to investigate the behavior of Williamson fluid model convoyed with thermal radiation, viscous dissipation and activation energy between sinusoidal walls. The electro-osmotic phenomenon is modeled through Poisson-Boltzmann equation. Electro-osmotic fluid has many applications such as, electro-osmotic fluid pumps, liquid medicine delivery, micro-fabricated fluid devices and lab-on-a-chip devices, etc. The model is produced by using a very relatively small Reynolds number and the long-wavelength approximation. Dimensionless transformations are used to reduce the system into dimensional form. DSolve command in MATHIMATICA and perturbation approach is used to simplify the governing equations. After applying the perturbation technique, graphs are used to illustrate the physical effects of temperature, velocity, concentration, pressure gradient, and streamline distribution. • The boundary-flow of Williamson fluid model across the micro-wavy channel having sinusoidal walls. • We discuss the zones of human beings and in the nervous system. • The equations are solved by the assumption of long-wavelength approximation and very small-Reynolds number.
