“…Further, in these heat pipes with Na, NaK and K, the only relevant and mostly used wall materials are nickel, niobium and stainless steel [12,13]. In such heat transfer devices, not only the fluid properties but also the properties of the wall such as its thermal conductivity and thickness also influence the heat flux transported by the fluid and hence the problem becomes a 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.

“…When the encapsulation material is determined, its resistance to corrosion or embrittlement caused by liquid Ga is one of the most important criterion because the damage of encapsulation by liquid Ga during the proton irradiation can induce serious breakage of accelerator vacuum system. In this research, Ti and Mo were chosen as candidate encapsulation materials in addition to Nb, the conventional choice for the encapsulation of Ga [4] because of the following reasons: Ti, Mo, and Nb are known to have satisfactory resistance to attack by Ga at temperatures up to 400 ∘ C [6]. Moreover, Ti is known to resist embrittlement by liquid Ga [7].…”

is study investigates the effect of liquid gallium (Ga) on metal foils made of titanium (Ti), niobium (Nb), and molybdenum (Mo). e Ti, Nb, and Mo foils were heated in liquid Ga at 120 ∘ C for a maximum of two weeks. Aer heating, the changes in the morphology and the chemical composition of the metal foils were analyzed by using a �eld emission scanning electron microscope, energy-dispersive X-ray spectrometer, X-ray diffractometer, and X-ray photoelectron spectrometer. e results of the analysis indicated that the Nb foil showed the minimum adhesion of liquid Ga to the surface while the maximum amount of liquid Ga was observed to adhere to the Ti foil. In addition, the Nb foil was oxidized and the Mo foil was reduced during the heating process. Considering these effects, we conclude that Mo may be used as an alternative encapsulation material for Ga in addition to Nb, which is used as the conventional encapsulation material, due to its chemical resistance against oxidation in hot liquid Ga.
