Peristaltically driven flow of hybrid nanofluid in a sinusoidal wavy channel with heat generation

The present analysis is reported to analyze the hybrid nanofluid (SiO ₂ − CNT/H ₂ O) flow as peristaltic transport under the influence of heat generation/absorption in a sinusoidal wavy channel. We have expressed the non-dimensional equations into two dimensional coordinate system by using vary long wavelength (δ < 1) and low Reynolds number $\left(Re\right)$ assumptions. The non-dimensional hybrid nanofluid (SiO ₂ − CNT/H ₂ O) equations are solved approximately by using well known perturbation approach. The numerical solutions for temperature and two dimensional peristaltic flow are obtained by using Mathematica software. The obtaining solutions for temperature and peristaltic transport are expressed graphically with help of Matlab software. The graphical results show that pressure rise, temperature profile and pressure gradient of hybrid nanofluid (SiO ₂ − CNT/H ₂ O) flow increases due to increase of heat generation. The pressure rise and pressure gradient of hybrid nanofluid decreases due to increase of phase difference ϑ. Furthermore, pressure gradient and pressure rise of SiO ₂ − CNT/H ₂ O hybrid nanofluid also decreases by increase in channel width. The streamlines for peristaltic transport are also elucidated in present analysis. The streamlines show that bolus size increases due to increase of amplitude but decreases by increase of heat generation. (paper)
