“…The reason is that, with the increase of magnetic force parameter, the magnetic energy increases, which extracts the kinetic energy of the fluid; thus, the coefficient of skin friction, rate of heat transfer, and current density are increased. Table 10 presents the results obtained in present study and the results obtained by Chawla [31], and we can see that the results obtained by both authors are in good agreement. Similarly, Table 11 shows the results obtained by present authors and the results obtained by Tan and Wang [32] for the distribution of the dimensionless temperature parameter θ for Pm 1.…”

The natural convection flow from a magnetized sphere in the presence of thermal radiation is considered. The characteristics of boundary-layer flow in the form of skin friction, rate of heat transfer, and current density at different positions of the sphere are evaluated. The numerical solutions of velocity profile, temperature distribution, and transverse component of the magnetic field are also presented. In the present study, the finite-difference method is used to find the numerical solutions of the flow model.

“…Developments in MHD when the free stream is oscillating have been discussed. Chawla (1971) All the quantities have their usual meaning except that U , is now the mean velocity. Assuming a weak oscillatory flow to be superimposed on the mean steady flow, the above equations were separated into a set of equations representing the mean flow and the unsteady flow.…”

“…The physical behavior of heat transfer in unsteady boundary-layer problem past a heated vertical plate under surface temperature oscillations has been investigated theoretically [2]. Chawla [3] analyzed an oscillatory flow problem of electrically conducting fluid along a flat-plate with harmonic oscillation effects by using Karman-Pohlhausen method analytically. Pedley [4] discussed free stream velocity effects on 2-D boundary-layers flow which oscillates without reversing numerically.…”

“…Taking idea from the aforementioned literature review, it is addressed that the surface temperature oscillation and free stream velocity effects on oscillatory free-forced convective slip-flow along a horizontal non-conducting circular cylinder has not been yet examined by any researcher. Taking idea from the following [3,16], we obtained a numerical method for previous slip-flow phenomena around a horizontal non-conducting circular cylinder under slip-velocity. We explore fluid slip-velocity, temperature and magnetic velocity which are used to conclude oscillating quantities of skin friction, fluctuating heat transfer and oscillatory current density.…”

The present phenomena address the slip velocity effects on mixed convection flow of electrically conducting fluid with surface temperature and free stream velocity oscillation over a non-conducting horizontal cylinder. To remove the difficulties in illustrating the coupled PDE, the primitive variable formulation for finite dif?ference technique is proposed to transform dimensionless equations into primitive form. The numerical simulations of coupled non-dimensional equations are exam?ined in terms of fluid slip velocity, temperature, and magnetic velocity which are used to calculate the oscillating components of skin friction, heat transfer, and cur?rent density for various emerging parameters magnetic force parameter, ?, mixed convection parameter, ?, magnetic Prandtl number, ?, Prandtl number, and slip factor, SL. It is observed that the effect of slip flow on the non-conducting cylinder is reduced the fluid motion. A minimum oscillating behavior is noted in skin friction at each position but maximum amplitude of oscillation in heat transfer is observed at each position ? = ?/4 and 2?/3. It is further noticed that a fluid velocity increas?es sharply with the impact of slip factor on the fluid-flow mechanism. Moreover, due to frictional forces with lower magnitude between viscous layers, the rise in Prandtl number leads to decrease in skin fiction and heat transfer which is physi?cally in good agreement.
