“…In fact, it has been firmly established that the effect or level of conjugation, in general, is more pronounced in the case of unsteady, laminar flow of low Prandtl number fluids such as liquid metals [33] and the present problem satisfies all these requirements for a typical conjugate heat transfer problem.…”

The combined effect of conjugation, external magnetic field and oscillation on the enhancement of heat transfer in the laminar flow of liquid metals between parallel plate channels is analyzed. In order to make our results useful to the design engineers, we have considered here only the wall materials that are widely employed in liquid metal heat exchangers. Indeed, all the results obtained through this mathematical investigation are in excellent agreement with the available experimental results. The effective thermal diffusivity κ e is increased by 3 · 10 6 times due to oscillation and that the heat flux as high as 1.5 · 10 10 (W/m 2 ) can be achieved. Based on our investigation, we have recommended the best choice of liquid metal heat carrier, wall material and its optimum thickness along with the optimum value of the frequency to maximize the heat transfer rate. At the optimum frequency, by choosing a wall of high thermal conductivity and optimum thickness, an increase of 19.98% in κ e can be achieved. Our results are directly relevant to the design of a heat transfer device known as electromagnetic dream pipe which is a very recent development.

“…One of the analytic approaches that are used in conjugate heat transfer problems creates a second boundary condition by introducing an unknown function [26]. Following this method, the two unknown functions ju 1 ðl 1 ; tÞj max ¼ aUðtÞ jp 2 ðl 1 ; tÞj max ¼ aPðtÞ (3.6) defining the final velocity and pressure amplitudes at the flame are applied as additional boundary conditions.…”

“…This conjugate approach substituted the empirical heat transfer coefficient after computer came in use. Beginning from simple examples in sixties, the conjugate approach currently becomes a powerful tool for solving industrial and scientific problems and is extensively used in different applications [26].…”

“…Conjugated heat transfer problems and fluid axial conduction are also faced in mini or microtubes, because of relatively thick walls, small diameters and therefore low Reynolds and Peclet numbers in flows. Brief literature surveys for laminar pipe or channel flows are given by Shah and London [11] and for conjugate problems by Dorfman [12], Weigand and Gassner [13] and Bilir [14,15].…”
