In this work, we studied the impact of Hall current, diffusion thermo, and activation energy on an electrically conducting Casson nanofluid flow past a continuously stretching surface with thermal radiation, and heat generation/absorption has been explored. Transverse magnetic field with the assumption of small Reynolds number is implemented vertically. Appropriate similarity transformations are utilized to transform the governing partial differential equations into the non-linear ordinary differential equations. Numerical solutions for the dimensionless velocity, temperature and nanoparticle concentration are computed with the help of the shooting method. Through the use of graphs, the discussion will focus on the effects that the Hall current, the thermal radiation, the heat source/sink, the Brownian motion, the thermophoresis parameter, and the magnetization have on velocity, concentration, and temperature. To get an insight into the internal behavior of the emerging parameters, a numerical calculation of the local Nusselt number, the Sherwood number, and the skin friction coefficient along the x-and z axes is performed. It has been shown that the resultant flow velocity enhances with increasing hall parameter, whereas it has reduced in temperature and concentration field. The temperature diminishes with improving diffusion thermo parameters, and the opposite behavior has been observed in the case of thermal radiation.

“…The formulated fluid model is converted into a pair of ODEs by adopting appropriate similarity variables. The coupled ODEs are numerically manipulated with the aid of BVP4C MATLAB built-in technique [49][50][51][52][53]. A graphical inquiry into the evolving parameters with respect to temperature distribution, concentration distribution, and velocity profile is established and discussed.…”

An investigation of an axisymmetric mixed convective boundary layer flow of silver-titanium dioxide/water (Ag−TiO2/H2O) hybrid nanofluid towards vertically and rotating stretching cylinder with entropy generation is conducted. The Cattaneo-Christov theory and joule heating effect are used to analyze the features of thermal energy. Moreover, the magnetic impact and convective boundary conditions on the vertical surface also considered in the current investigation. The developing equations for momentum, energy and entropy generation are modelled and by the usage of similarity variables to transform into the system of nonlinear ordinary differential equations (ODEs). The solutions of nonlinear ODEs are obtained numerically with the assistance of BVP4C MATLAB built-in scheme. The graphical consequences and relevant physical reasoning regarding the velocity, temperature, and concentration profiles are discussed. It is noteworthy that strong estimation of buoyancy ratio and mixed convection parameter enhances axial velocity, but the swirl velocity is diminished. The fluid temperature and concentration both are diminished due to thermal and solutal stratification effects. It is also seen that thermal Biot and Eckert numbers enhance the temperature distribution. Further, the Reynold number improves entropy generation.

“…They observed that the temperature enhanced for higher values of radiation parameter and also the rate of heat transfer decreases with an increase in thermal conductivity parameter. Shafiq Ahamad et al 26,27 investigated the radiative heat transfer characteristics of SWCNT and MWCNT hybrid nanofluid with temperature dependent viscosity. They noticed that the velocity profile diminishes with an increase in solid volume fraction and temperature enhances for an increase in solid volume fraction.…”

The Present work addresses the MHD three-dimensional boundary layer flow of Powell Eyring fluid over a bidirectional non-linear stretching surface in the presence of thermal radiation and heat generation/absorption. We also considered the temperature dependent thermal conductivity. The governing flow partial differential equations are transmuted into ordinary differential equations with the help of suitable similarity transformations. The resultant non-linear coupled system is solved numerically by the shooting technique. This article presents the novel exploration of radiative heat transport of Powell Eyring fluid by considering temperature dependent conductivity over a bidirectional non- linear stretching sheet. The effects of various pertinent parameters on the present flow are presented graphically and explained in detail. We noticed that the velocity and temperature fields can be reduced by applying a strong magnetic field. The progress in Prandtl number condenses the temperature field but it improves the rate of heat transfer. Further, it is concluded that the large values of Powell Eyring fluid parameters enhance the skin friction.
