The effect of conjugation on the enhancement of heat transfer in a liquid metal flow past a thermally conducting and sinusoidally oscillating infinite flat plate, when a constant temperature gradient is superimposed on the fluid, is investigated. The plate is made up of the materials compatible with the liquid metals used and is considered to be of finite thickness. Analytical solutions for the velocity and the temperature of the fluid and the solid are obtained. The effects of thermal conductivity and the thickness of the plate on the total time averaged heat flux transported and the thermal boundary layer thickness are investigated in detail. It is found that the effects of wall thickness and wall thermal conductivity on the heat flux transported depend on their effects on the transverse temperature gradient at any frequency. The optimum value of wall thickness at which the net heat flux transported attains the maximum value, for each fluid and for each wall material under consideration, is reported. A maximum increase of 46.14%in the heat flux transported can be achieved by optimizing the wall thickness. A maximum convective heat flux of 1:87×108W/m2 is achieved using Na with AISI 316 wall. All the results obtained have been compared with the experimental and analytical results reported in the literature and are found to be in good agreement. It is believed that the new insights gained will be of significant use while designing liquid metal heat transfer systems.

P. Puvaneswari and Dr. Shailendhra K., “Enhancement of Heat Transfer in a Laminar Hydromagnetic Flow of a Liquid Metal Past a Thermally Conducting and Oscillating Infinite Flat Plate”, Heat Transfer - Asian Research, 2016.[Abstract]


The combined effects of conjugation and magnetic field on the heat transfer enhancement in a laminar liquid metal flow past a thermally conducting and sinusoidally oscillating infinite flat plate are investigated. The wall materials used are compatible with the liquid metals and are assumed to be of finite thickness. Analytical solutions are obtained for the velocity and the temperature distributions. The combined effects of thermal conductivity, the thickness of the plate, and the transverse magnetic field on the net heat flux transported are analyzed in detail and it is found that such effects are same as those on the transverse temperature gradient at any frequency. Due to oscillation, the heat flux is enhanced by O(103). The optimum value of wall thickness and the corresponding boundary layer thickness for which the maximum heat flux is obtained are reported. The heat flux transported can be increased by choosing a wall of low thermal conductivity. A maximum increase of 52.03% in heat flux can be achieved by optimizing the wall thickness. These information may be useful while designing magnetohydrodynamic liquid metal heat transfer systems. All the results obtained are in good agreement with the results reported earlier.

The effects of Hartmann number, porous parameter and Darcy velocity on the steady flow of a viscous incompressible slightly conducting fluid through a uniform channel bounded by porous media of finite thickness under a uniform ransverse magnetic field are considered. It is assumed that the thickness of the porous media is much smaller than the width of the flow channel as in the case of blood flow in arteries and accordingly the BJR slip boundary condition has been employed. The effects of all the above parameters on the axial velocity of the flow and the shear stress have been investigated. Finally, these results are compared with a earlier problem of MHD flow through a uniform channel covered by porous media of infinite thickness where the BJ slip boundary condition has been employed.

The enhanced heat transfer in the oscillatory flow of liquid metals between two thermally insulated infinite parallel plates, when a constant axial temperature gradient superimposed, is investigated. The fluid is set to oscillation by oscillating both the plates axially along with an axial oscillatory body force, having the same frequency as that of the plates. The effective average thermal diffusivity is calculated and the effect of oscillation of the plates and the oscillatory body force on the enhancement of heat transfer are discussed and compared.

The convective MHD flow past a uniformly moving infinite vertical porous plate with Hall current, viscous dissipation, heat source and variable suction has been analyzed. The free stream velocity oscillates about a mean value. A pulsated suction is taken into account. Analytical solutions are obtained using perturbation method. The effects of Hall current over primary velocity, secondary velocity, and heat transfer amplitude and phase are analyzed. Effects of heat source parameter, Eckert number, and Prandtl number on the velocity components and temperature are also examined. More »»

K. Ramakrishnan and Dr. Shailendhra K., “Hydromagnetic flow through uniform channel bounded by porous media”, Applied Mathematics and Mechanics, vol. 32, no. 7, pp. 837–846, 2011.[Abstract]


The combined effects of the magnetic field, permeable walls, Darcy velocity, and slip parameter on the steady flow of a fluid in a channel of uniform width are studied. The fluid flowing in the channel is assumed to be homogeneous, incompressible, and Newtonian. Analytical solutions are constructed for the governing equations using Beavers-Joseph slip boundary conditions. Effects of the magnetic field, permeability, Darcy velocity, and slip parameter on the axial velocity, slip velocity, and shear stress are discussed in detail. It is shown that the Hartmann number, Darcy velocity, porous parameter, and slip parameter play a vital role in altering the flow and in turn the shear stress. More »»

In recent years, several investigations were carried out to study the characteristics of a novel heat transport mode in which heat is transported from a hot to a cold reservoir by means of sinusoidal oscillations of a viscous fluid contained within open-ended tubes connecting the reservoirs. It has been experimentally[1] and analytically [2] confirmed that such periodic longitudinal oscillations result in a very significant enhancement in axial transport capability of the fluid. More »»
