Content available Heat transfer in oscillating flow through porous medium with dissipative heat

Vol. 27, no. 2
77--86
EN
In this paper, heat transfer in flow between two horizontal parallel porous plates through a porous medium when the upper plate oscillates in its own plane has been analyzed taking into account the effect of viscous dissipation. An increment in the Prandtl number or Reynolds number results in an increment of the temperature profile. With an increase in viscous dissipative heat the temperature distribution decreases.

EN
An analysis is made on the three dimensional flow of a viscous incompressible fluid through a vertical channel in the presence of radiation in slip flow regime. The right plate is subjected to an uniform injection and the left plate to a periodic suction velocity distribution. The velocity and temperature fields have been derived using the perturbation technique. It is found that the velocity decreases with the increase of the slip parameter. It is also found that the velocity decreases with the increase of the radiation parameter but near the right plate it increases. For cooling of the plate, the velocity increases with the increase of the Grashoff number and decreases near the right plate but the reverse effect is observed for heating the plate.

An analysis of a three-dimensional Couette flow with radiation effect on temperature distribution in the presence of heat source/sink is analysed, when the injection of the fluid at the lower stationary plate is transverse sinusoidal and its corresponding removal by constant suction through the porous plate in uniform motion. Due to this type of injection the flow velocity becomes three-dimensional. The effect of the Prandtl number, injection and source/sink parameters on the rate of heat transfer is examined. The Prandtl number has a much greater effect on the temperature distribution than the injection or source/sink parameters.

An analysis is made on the three dimensional MHD flow of a viscous incompressible fluid through a vertical channel in the presence of a uniform injection on the right plate and the left plate is subject to a periodic suction. The velocity and temperature fields are derived using the perturbation technique. It is observed that the primary velocity increases near the left plate and decreases near the right plate with an increase in the Reynolds number while it decreases with an increase in the magnetic parameter. It is seen that with an increase in the Prandtl number the primary velocity decreases whereas it increases with an increase in the Grashof number. It is seen that the magnitude of the secondary velocity increases in the range […] and thereafter decreases with an increase in the Reynolds number. It is also seen that the shear stress due to primary flow increases with an increase in either the Grashof number or Reynolds number but decreases with an increase in the Prandtl number. It is seen that the shear stress […] at the plate […] decreases with an increase in the magnetic parameter. Also, the magnitude of the shear stress due to cross flow increases with an increase in the Reynolds number. It is seen that the temperature at any point decreases with an increase in either the Prandtl number or Reynolds number. The rate of heat transfer in terms of the Nusselt number is also studied. Dimensional variables are indicated by dropping the asterisk and are defined in Eq.(2.8).

EN
A study of the temperature jump boundary condition is made on a three dimensional free convection flow between two vertical parallel porous flat plates. At the stationary plate there is a transverse sinusoidal injection and its corresponding removal is at the other plate. Using series expansion, the expressions for velocity and temperature distributions, the skin friction and rate of heat transfer are obtained. It is observed that an increase in the jump temperature increases the Nusselt number at the stationary plate.
