Entropy generation analysis on electroosmotic flow in non-Darcy porous medium via peristaltic pumping

Abstract

In current paper, it is aimed to investigate the entropy generation of electroosmotic flow aggravated by peristaltic pumping across a non-Darcy porous medium. We have implemented the Darcy Forchheimer model to interpret the permeability of porous media. The electro-magneto-hydrodynamic flow is considered in a symmetric channel. We have analyzed the flow characteristics, heat transfer and entropy generation for various values of joule heating parameter $$\gamma$$ , Hartmann number $$H_{\text{m}}$$ , Darcy number $$\Omega^{2}$$ , Forchheimer number $$c_{\text{F}}$$ and electroosmotic parameter m. It is found that entropy generation increases for increasing values of Darcy number $$\Omega^{2}$$ and Forchheimer number $$c_{\text{F}}$$ .
