Entropy generation and chemical reaction effects on MHD non-Newtonian nanofluid flow in a sinusoidal channel

Abstract

This article discusses the effects of entropy generation as well as slip velocity condition on MHD Jeffery nanofluid flow through a porous medium in a channel with peristalsis. We take the effects of mixed convection, heat source, double diffusion and chemical reaction into consideration. Using the assumption of low-Reynolds number and long-wavelength, series solutions of the governing equations are obtained via homotopy perturbation method. Results will be discussed at various parameters of the problem and drawn graphically. Physically, our model is consistent with the motion of digestive juice in the bowel whenever we are going to insert an endoscopy through it. It is noticed that the axial velocity magnifies with an increase in the values of both first and second slip parameters. Meanwhile, the value of the axial velocity reduces with the elevation in the values of both Grashoff and Darcy numbers. On the other hand, the elevation in the value of thermal radiation leads to a reduction in the value of fluid temperature. Furthermore, increasing in the value of order of chemical reaction parameter makes an enhancement in the value of the solutal concentration. It is noticed also that the entropy generation enhances with the increment in the value of Eckert number. The current study has many accomplishments in several scientific areas like engineering industry, medicine, and others. Therefore, it represents the gastric juice motion depiction in the human body when an endoscope is inserted through it.

Thermal micropolar couple stresses effects on peristaltic flow of biviscosity nanofluid through a porous medium

“…It observed from these figures that the effect of Ec and R is similar to the effect of  and Nt on T in the first interval, respectively. It is clear that the temperature is decreases by increasing Ec and increases by increasing R till a value of r, after which it decreases by increasing Ec and increases by increasing R. The effects of both M and Nb on the temperature distribution are found to be similar to effect of Nt given in the figure (6) while the effects of β is likes to  given in the figure (7).…”

“…The system of ordinary differential equations (10-13) is converted/ non-dimensional by appropriate similarity variables subject to boundary conditions (14)(15). Initial conditions/first order of differential equation is obtained via superposition technique and then GDTM algorithm is used to extract the higherorder values.…”
