Effect of radial magnetic field on natural convection flow in alternate conducting vertical concentric annuli with ramped temperature

A numerical study of magneto‐double‐diffusive‐convection of Casson fluid over a vertical cone under nonuniform heating at surface of cone

“…The effect of on the velocity is illustrated by Figure 2A and it is observed that the velocity profile decrease for increasing value of . This is due to a resistive force, named Lorentz force, generated between the fluid layers similar result is obtained from Vatsa and Kumar 18 . However, the effect of small values of along the different cross sections gives a significant consequence while for the large values of , the effect vanishes over the cross section.…”

“…Also, for higher values of time, the velocity and temperature profiles move toward steady state (see Figure 5A,B). From Figure 5C, we can see that the concentration profile is increasing upto with time parameter and afterward, it is decreasing for higher values of time, which is a new result as Vatsa and Kumar 18 have shown that the concentration profile attains its maximum at t = 1 and decreases after = 1. The impact of various parameters (, and ) on local skin‐friction () against is represented in Figure 6.…”

“…The research of free convective MHD flow in different geometries in the presence of a magnetic field under different physical situations has been found in Ref. [15][16][17][18][19][20][21]. Prakash et al 22 studied the impact of magnetic field on free convective flow over a vertical cone for variable heat and mass flux and obtain the variation on the velocity, concentration and temperature profile for various physical parameters.…”

Heat and mass transport performance of MHD elastico‐viscous fluid flow over a vertically oriented magnetized surface with magnetic and thermo diffusions

“…Regular perturbation analysis is utilized for solving the leading flow governing Equations ( 17) and (18). We consider the two-term perturbation solution of velocity and induced magnetic field with very small suction/blowing parameter S as follows:…”

“…The induced magnetic field significantly alters the presence of the applied magnetic field and places a decisive role in analyzing the flowing nature. Enthused from these facts many scientists [13][14][15][16][17][18][19][20][21][22][23][24] examined the IMF effects on the MHD fluid flow behaviors. Recently, Singh et al 25 scrutinized the mixed convective flow within a channel with varying wall thickness and conductance and found that the wall conductance constant significantly enhances the IMF along the principal flow direction.…”
