Enhancement of Heat Transfer in a Liquid Metal Flow past a Thermally Conducting and Oscillating Infinite Flat Plate
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 wi...

| description | 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. |
