Magnetohydrodynamic experimental design and program for Chinese liquid metal LiPb experimental loop DRAGON-IV

“…[13]. By calculation with MTC software [13], the inlet velocity of air cooled system was 0.125 m/s, the temperature out of the heat insulation layer was 26 • C, and the maximum stress was about 73 MPa at the edges of the duct, which was much lower than the allowance value of the 316 L steel, i.e. about 200 MPa under 350 • C.…”

“…3 One of its applications in material processing could be the control of fluid flow by the magnetic field. Researchers have been applied different approaches for solving MHD problems such as analytical methods, 2,4-6 numerical, 7,8 and experimental 9,10 methods. The first research on the divergent channel was done by Jeffrey 11 and Hamel.…”

Due to the pressure gradient increasing downstream, the boundary layer separation phenomena may occur on the divergent channel flow wall. Still, several methods have been applied to control or postponed the separation. Exerting a magnetic field on the fluid flow is one solution. In the present research, we aim to investigate the impact of magnetic fields on the separation location in a divergent channel numerically. Hence, the finite volume method using the OpenFOAM CFD toolbox is employed, and a code for 2-D divergent channel flow under a non-uniform magnetic field is developed. The obtained results have been validated in comparison with previous studies. The results are presented for a test case of the channel with divergence half-angle equals 2.5°, 30 cm length, and 2 cm inlet height. It is demonstrated when Ha increases from 0 to 2, the separation points for liquid lithium fluid flow with Re = 208.33 are postponed from 12.93 cm to 23.18 cm. Moreover, it is shown that the separation phenomena disappear entirely for the Ha value of more than 3.

“…In this paper, we investigated MHD pressure drop of PbLi flow in an electrically conducting rectangular duct under a transverse magnetic field on loop DRAGON-IV [26][27][28]. The present experiment was to validate the differential pressure measurement approach for high-temperature (300-600°C) liquid PbLi MHD flow.…”

Liquid metal flow of blanket in fusion reactor would bear pressure drop caused by magnetic field. To investigate the magnetohydrodynamic (MHD) pressure drop characteristics, experiments of PbLi flow in an electrically conducting rectangular pipe subjected to a transverse magnetic field were performed on loop DRAGON-IV. A measurement approach for differential pressure in high temperature liquid PbLi was adopted, and detailed data on pressure drop in PbLi MHD flow under various magnetic fields were measured. Electric potential method in the experimental pipe was adopted to measure the flow rate. The obtained experiment results for the MHD pressure drop were in good agreement with theory calculation. Through theoretical analysis, it has been found that the temperature of experimental pipe has a remarkable impact on MHD pressure drop. The change of temperature from 430 to 650°C can lead to a decrease of MHD pressure drop by 10 %. Further experimental studies on the temperature effect on MHD pressure drop are needed.
