In this paper, we investigate steady free convective Couette flow in a vertical channel with nonlinear thermal radiation, dynamic viscosity and dynamic thermal conductivity effects. The investigation is motivated by the studies of some researchers which assumed linear thermal radiation and constant fluid properties. However, this is uncalled for; as these assumptions do not reflect true behavior of the flow. For instance; increase in temperature affects fluid viscosity, thermal conductivity thereby changing the transport phenomenon. Here; the investigation considers both the fluid viscosity and thermal conductivity to be dependent on temperature with the thermal radiation adopting nonlinear form. Due to this reasons, the associated flow equations are highly nonlinear and exhibit no analytical solution and therefore require the use of Adomian decomposition method (ADM) of solution. The attained ADM solution is then coded into computer algebra package of mathematica where results under the parameters of interest are presented and discussed. Results of the investigation show that raising the thermal radiation leads to corresponding rise in both the velocity and temperature of the fluid in the channel. Furthermore; lessening the viscosity and thermal conduction of the fluid were identified to escalate both velocity and temperature of the fluid.

“…Cassons constitute equation represents a nonlinear relationship between the rates of stress and strain and has been noticed to be accurately applicable in silicon suspensions and lithographic varnishes used for printing inks. Ajibade and Bichi [1] investigated the variable fluid properties and thermal radiation effects on natural convection Couette flow through a vertical porous channel using the Adomian decomposition method (ADM) and maintained that both fluid velocity and its temperature within the channel were observed to increase with growing thermal radiation and decreases with increase in thermal conduction of the fluid. Yusuf et al [2] examined the boundary layer flow of a nanofluid in an inclined wavy wall with convective boundary condition.…”

This study investigates the temperature viscosity and Hall effects of a Casson fluid flow through a porous medium of a viscous incompressible fluid bounded by two parallel porous plates under the influence of thermal radiation and chemical reaction. A uniform suction and injection are applied perpendicular to the plates while the fluid motion is subjected to variable pressure gradient. The transformed conservation equations are solved analytically subject to physically appropriate boundary conditions by using perturbation and Eigenfunction expansion techniques. The influence of a number of emerging non-dimensional parameters namely, variable pressure gradient parameter, suction parameter, radiation parameter and Hartman number are examined. It is observed that the primary velocity profile is increased with increasing temperature dependent viscosity while increase in Hall parameter leads to increase in secondary velocity profile of the flow.

“…Reddy et al (2017) investigated unsteady MHD heat transfer in Couette flow of water at 4 O C in a rotating system with ramped temperature. Ajibade and Bichi (2019) examined natural convection Couette flow through a vertical porous channel due to combined effects of thermal radiation and variable fluid properties. Recently, Xia (2021) reported gear-generalized differential quadrature analysis of oscillatory convective Taylor-Couette flows.…”

The effect of heat source on unsteady hydromagnetic convective Couette flow of a viscous, electrically conducting and incompressible fluid is investigated. The governing equations that explain the flow formation are modeled as Partial Differential Equations (PDEs) and solved numerically by Finite Element Method (FEM). The influence of physical parameters on the fluid velocity, temperature and concentration were presented graphically and discussed. It is seen that, the momentum and temperature boundary layers are significantly influenced as the value of heat source parameter is increased while an opposite trend is observed on the velocity as Hatman number is increased.
