“…They found that the fluid velocity increases with stretching parameter. The analytical outcomes of MHD copper-water nanofluid flow through two non-comparable converging/diverging channels with the help of RVI method was proposed by Azimi and Riazi [4]. They noted that increase in Eckert number resulted into increase in the values of Nusselt number.…”

This article unveils the combined impact of heat generation/absorption and Joule heating on MHD flow of Ag-H 2 O nanofluid into a porous stretching/shrinking divergent/ convergent channel with viscous dissipation and solid volume fraction. The mathematical modeling is presented for the existing equations of continuity, momentum, and energy fraction. The reduced boundary value problem is solved numerically employing Runge-Kutta-Fehlberg (RKF) method via shooting scheme and then the outcomes are sketched and interpreted. The results explore that the thermal boundary layer thickness of the stretching divergent and the shrinking divergent channels enhance by increasing the value of the Eckert number, while the opposite tendency is scrutinized on the momentum boundary layer thickness by increasing the value of the porosity parameter for the stretching divergent and the shrinking convergent channels.

“…In their analysis for the MHD nanofluid flow in a rotating channel, Raza et al [19] considered slip effects. When Azimi and Riazi [20] increased the Reynolds number, skin frictions and Nusselt numbers were found to be enhanced. Dogonchi et al [21] analysis of MHD nanofluid flow in a porous canal took the thermal radiation effect into account and found an inverse relationship between the radiation and the temperature profile.…”

This work investigates the generation of entropy in the presence of a heat source/sink in a sloping channel filled with porous medium in magnetohydrodynamic nanofluid flow. The regulating equations are nonlinear and coupled thermal and hydrodynamic equations. Homotopy analysis method is used in the handling of equations. Comparisons with existing literature have been produced and were discovered to be in excellent accord, which are a particular situation of the present issue. The impact on entropy generation, Bejan number, Nusselt number and skin friction of pertinent fluid parameters is addressed, developed and displayed graphically. Entropy generation was found to be minimum just above the center of the channel throughout the study. Skin friction and Nusselt number were found to be higher for the case of heat generation than heat absorption.

“…Azimi et al [26] investigated the velocity profile in MHD Jeffery Hamel flow with nanoparticles by using DTM. Also, Azimi and Riazi [27] obtained the analytic approximate solutions of two-dimensional magnetohydrodynamic copper-water nanofluid flow between convergent and divergent channels using RVIM. In another article, Azimi and Riazi [28] reported heat and mass transfer analysis of MHD unsteady viscous fluid squeezed between two parallel plates.…”

In the present paper, we investigated unsteady three-dimensional flow of an incompressible magneto Maxwell nanomaterial in the porous medium. The cause of flow is unsteady stretching of sheet in transverse lateral directions taking zero mass flux of nanoparticles. The developed system of partial differential equations is transformed into nonlinear ordinary differential equations by similarity variables, and the obtained system is solved for dimensionless temperature and nanoparticles concentration by homotopy analysis method. The behavior of physical parameters on the temperature and nanoparticles concentrations is examined through graphs and tabular data. The temperature distribution at the surface is also computed and analyzed and noticed that both the temperature and nanomaterial are reduced for higher values of unsteadiness parameter.
