EHD peristaltic flow of Sisko fluid under the effects of convection and endoscope

Abstract

The influence of an external normal electric field on peristalsis involving Sisko fluid on convection flow between two coaxial cylinders is explored. The resulting system of equations is analytically solved using the regular perturbation technique with low parameters. This approach is dependent on two factors: a small wave number and a small Sisko fluid parameter. Analytical solutions for radial and axial velocities, temperature, electric potential, and pressure are produced based on the use of appropriate non-dimensional quantities. Graphical representations of the impacts of various parameters on the pertinent physiological factors. The results show that when there is an electric field present, the effects of the endoscope velocity on the axial velocity are more noticeable and distinct than when there isn't. It is discovered that the endoscope radius plays a dual role on the electrical potential. The electrical potential decreases with an increase in the endoscope velocity, amplitude ratio, Reynolds number, and Prandtl number while the opposite occurs when electrical potential, temperature parameter, and power index are increased. Additionally, with respect to shear thickening fluid, the temperature, electrical potential, and pressure are all higher compared to in the case of Newtonian fluid. The Rayleigh number, electrical potential, endoscopic velocity and radius, temperature parameter, Reynolds number, and power law index all raise the size of the trapped bolus while the amplitude ratio diminishes it. The study's findings will assist in a better understanding of biomedical engineering and technology.
