Effects of Hall current and ion-slip on the peristaltic motion of couple stress fluid with thermal deposition

This paper explores the peristaltic motion of couple stress fluid in an inclined asymmetric channel relevant to blood arteries. Mathematical modeling is developed under the Hall and ion-slip aspects. Further to explore heat and mass transfer mechanism thermal deposition, Joule heating, and chemical reaction effects are also outlined. In addition channel boundaries are set to convective conditions. After invoking long wavelength and low Reynolds number, the resulting non-linear system has been approximated numerically. Thus graphical illustrations subject to axial velocity, temperature, concentration, and heat transfer rate have been sketched and physical interpretation for emerging variables of interest is made. The significant feature of this study reveals the activation of velocity and reduction of temperature with larger Hall and ion-slip parameters. The heat and mass transfer Biot numbers show opposite behavior towards temperature.
