“…The effects of heating, mass, and skin drag factors on boosting the values of various quantities were explored. Shah et al [6] numerically analyzed the hydro-magnetic mixed convective Maxwell fluid movement on a vertically stretched surface with a varying thickness close to a stagnation point. It was discovered that at larger values of the Maxwell and thermal conductivity factors, the temperature rises.…”

Due to excessive heating, various physical mechanisms are less effective in engineering and modern technologies. The aligned electromagnetic field performs as insulation that absorbs the heat from the surroundings, which is an essential feature in contemporary technologies, to decrease high temperatures. The major goal of the present investigation is to use magnetism perpendicular to the surface to address this issue. Numerical simulations have been made of the MHD convective heat and amplitude problem of electrical fluid flow down a horizontally non-magnetized circular heated cylinder with reduced gravity and thermal stratification. The associated non-linear PDEs that control fluid motion can be conveniently represented using the finite-difference algorithm and primitive element substitution. The FORTRAN application was used to compute the quantitative outcomes, which are then displayed in diagrams and table formats. The physical features, including the phase angle, skin friction, transfer of heat, and electrical density for velocity description, the magnetic characteristics, and the temperature distribution, coupled by their gradients, have an impact on each of the variables in the flow simulation. In the domains of MRI resonant patterns, prosthetic heartvalves, interior heart cavities, and nanoburning devices, the existing magneto-hydrodynamics and thermodynamic scenario are significant. The main findings of the current work are that the dimensionless velocity of the fluid increases as the gravity factor Rg decreases. The prominent change in the phase angle of current density αm and heat flux αt is examined for each value of the buoyancy parameter at both α=π/6 and π angles. The transitory skin friction and heat transfer rate shows a prominent magnitude of oscillation at both α=π/6 and π/2 positions, but current density increases with a higher magnitude of oscillation.

“…One of the concluding remarks was that the skin friction coefficient is enhanced as the Maxwell parameter is augmented. Further reading interest can be found in [30][31][32][33][34][35].…”

In the present study, MHD Casson nanofluid under the influence of exponential temperature dependent thermal conductivity and variable viscosity past a stretching surface has been scrutinize. After the application of the similarity transformations, the governing partial differential equations of the modelled problem are converted into ordinary differential equations and solution is achieved with the assistance of the shooting method. The solution obtained with the help of shooting technique is used to analyze the distribution of mass and heat flux over sheet. The influence of various governing parameters on the dimensionless velocity, temperature and concentration distribution have been analyzed and discussed in detail. The simulations of the presented model show that the surface drag is upsurged as each of the Casson parameter and temperature dependent thermal conductivity parameter is boosted whereas the rate of heat transfer is diminished. It is also observed that an increment in the temperature near the surface is noted against the thermal conductivity parameter whereas an opposite trend is observed away from the surface.
