Краткое описание

Heat transfer analysis has been presented for the boundary layer combined convective flow of an electrically conducting liquid due to a porous vertical stretching plate with a power-law stretching velocity in presence of a transverse magnetic field. In the flow region, heat balance is maintained with thermal radiation. The similarity solutions for this problem are obtained by using a special form of Lie group transformations viz. scaling group of transformations. The equations are then solved numerically. With increasing values of the radiation parameter, the streamwise velocity as well as temperature decreases. At a particular point of the porous stretching sheet, the streamwise velocity decreases with the increasing suction parameter. The dimensionless temperature at a point of the sheet decreases due to suction but increases due to injection. With the increase of magnetic field intensity, the fluid velocity decreases but the temperature increases in both cases of suction and blowing. In the absence of magnetic field intensity and suction/ injection, the streamwise velocity displays a velocity maximum within the boundary layer when the stretching velocity power law exponent is negative. The findings of this study reveal that radiation and suction can be used as means of cooling the boundary layer flow region.
