Peristaltic Flow of Ethylene Glycol and Water Mixture-Based Hybrid Nanofluid in an Asymmetric Channel

This novel study examines the peristaltic magnetohydrodynamic hybrid nanofluid flow comprising the single-walled and multi-walled carbon nanotubes and an ethylene glycol–water mixture in an asymmetric channel in a permeable medium. The Xue model is considered for the thermal conductivity of carbon nanotubes. The heat transmission is evaluated in the presence of viscous dissipation and Joule heating. Moreover, at both walls of the channel, velocity and thermal slip conditions are assumed. The mathematical formulation is accomplished by employing a long wavelength and a low Reynolds number. We here will look into the impact of the varied parameters on associated profiles while considering the Xue model with binary mixture base fluid. The system of equations is solved using the built-in DSolve function in Mathematica to obtain its solution. The effect of pertinent flow parameters in the peristaltic flow phenomenon is graphically plotted and analyzed. Observations revealed that for the low magnetic parameter, the hybrid nanofluid flow would experience less pressure gradient load and for the high magnetic parameter hybrid nanofluid flow would experience more pressure. In addition, owing to higher estimations of the slip parameter, the velocity profile diminishes; however, an opposite outcome is witnessed for the porosity parameter.
