Blood-based electro-osmotic flow of non-Newtonian nanofluid (Carreau-Yasuda) in a tapered channel with entropy generation

Abstract

The motivation of current contribution is to signify the assessment of entropy generation in the flow of generalized Newtonian fluid generated under the influence of electro-osmosis and peristalsis. The flow has been confined by a tapered channel with certain flow assumptions. The fundamental conservations laws of mass, momentum, energy and concentration along with the Poisson and Nernst-Planck equations are used to identify the problem in given domain. The Poisson equation is solved analytically for potential function under the Debye-Huckel linearization approximation while the expressions are attained with association of conservation concept under widely used assumptions of minor Reynolds number and long wavelength. The velocity in axial direction, temperature and nanoparticles profiles are numerically approximated using shooting method. The electric force parameter and radiative constant are being expressed against different flow, temperature and concentration features via various sketches. The results for Newtonian and Carreau fluid as particular case are also presented via numerous plots and tables. It is expected that the obtained theoretical results are very useful for the resilience of medical instatements.
