Effect of heat and mass transfer on the MHD \(\mathrm{Al_2O_3/H_2O}\) and \(\mathrm{Al_2O_3/C_2H_6O_2}\) nanoliquid through an asymmetric vertical channel

Abstract

The impact of magnetic field on the peristaltic motion of alumina/water (\(\mathrm Al_2O_3/H_2O)\) and alumina/ethylene glycol (\(\mathrm Al_2O_3/C_2H_6O_2)\) nanofluids in a vertical asymmetrical channel with mass/heat transfer was examined in this study. Unsteady governing equations were derived for the present problem. The Galilean transformation was used to transform the unsteady governing equations into steady ones. Reducing partial differential equations yields ordinary differential equations with the implementation of the long wavelength and low Reynolds number approximations. Coupled nonlinear differential equations (concentration and temperature equations) were solved analytically using the perturbation technique. In a similar fashion, the exact solution to the stream function is computed. MATLAB software was used to plot temperature, pressure rise, velocity and concentration, while MATHEMATICA software was used for generating streamlines. The findings suggest that, in comparison to the \(\mathrm Al_2O_3/H_2O\) nanoliquid, the velocity profile for the \(\mathrm Al_2O_3/C_2H_6O_2\) nanoliquid shows significantly larger magnitudes.
