“…Jha et al [28] evaluated the natural convective viscous fluid flow past in an upright parallel plate channel. The significant existence of a magnetic force in a free convective, electrically conducting liquid flowing in an oblique channel was deliberated by Zaidi and Ahmad [29] and also discussed the outturn of different parameters including Nusselt number and skin friction. Monaledi and Makinde [30] used the Buongiorno model to study entropy in a Poiseuille flow of nanoliquid through a microchannel with injection and distribution and the outcome showed that skin friction was reduced by the accumulation of nanoparticles towards the center of the channel.…”

The tangent hyperbolic fluid model is interesting models in all the non-Newtonian fluid model, which is developed for particular applications in chemical engineering systems such as polymer solution, ceramic processing, fluid beds and oil recovery. Hence the intent of the present study is to explore the flow and thermal behavior of tangent hyperbolic fluid flowing through an upright microchannel. In the analysis, water and ethylene glycol are the base fluid with titanium and copper nanoparticles considered. The combined impact of nonlinear thermal radiation, no slip, buoyancy force, and Newton boundary condition on the thermal performance are studied, and further the skin friction and Nusselt number are examined. The thermal dependent heat source effect was also taken into account. The governing equations were solved numerically by employing Runge-Kutta Fehlberg’s fourth-fifth order. The impact of the pertinent constraint on the Nusselt number, thermal field, flow field, skin friction, Bejan number, and entropy generation are depicted graphically and examined. Entropy generation rises by 15% when ethylene glycol is a base fluid and 12% when the water a base fluid, with an enhancement of the Brinkman number by 200%. The outturn entrenched that the heat transfer rate in water-based hybrid nanofluid is more remarkable when compared with the heat transfer rate of EG-based hybrid nanofluid. It is noted that the significant increment in Nusselt number has been attained through a rise in the Weissenberg number and power law index.

“…Ali et al [17] utilized Galerkin weighted residual finite-element technique to analyze problems of heat transfer flow of nanofluid in the presence of natural convection. Zaidi and Ahmad [18] studied the effects of heat generation on buoyancy driven flow of viscous fluid through an inclined microchannel with slip conditions. Adegbie et al [19] analytically examined the impacts of pertinent fluid parameters on free convective flow of Newtonian fluid past a continuous moving surface.…”

The focus of the present study is to examine chemical reaction and Joule heating effects on steady flow of a viscous radiating fluid in a porous medium under the influence of variable viscosity. The fluid viscosity is assumed to vary exponentially with temperature. The governing equations of ow, heat and mass transfer are transformed into ordinary differential equations using appropriate similarity transformations. The converted ordinary differential equations are then solved numerically by using fourth order Runge-Kutta Fehlberg method. The effects of different pertinent parameters on the flow, heat and mass transfer characteristic are analyzed and discussed in detail through graphs and table. It is observed that larger values of variable viscosity parameter depreciates the fluid velocity.

In the present work, the effect of an oriented low magnetic field on near‐continuum gaseous slip flow inside a two‐dimensional rectangular microchannel has been studied using first‐order boundary conditions. The flow was assumed to be compressible, laminar, and steady. The governing equations were solved analytically to obtain the solutions of velocity, temperature, and the pressure of the flow. The influence of different parameters such as Knudsen number, aspect ratio, Hartmann number, and pressure ratio were studied and analyzed. It was found that the electric and magnetic field with an inclined angle had significant effects on the flow properties. The results showed that the velocity increases and the temperature decreases as the inclination angle of the magnetic field decreases. The velocity increases as the Knudsen number, pressure ratio, and aspect ratio increase, while it decreases with increasing of the Hartmann number. The temperature decreases with increasing of the Knudsen number, pressure ratio, and aspect ratio, while the temperature increases as the Hartmann number increases. The results of the present study were validated with published results in the literature.
