“…In addition, a high pressure drop induced by Lorentz force is the principal engineering difficulty to be solved. The liquid LiPb MHD experiments have been conducted in a rectangular pipe under transverse magnetic fields (ie, 0‐2 T) to investigate the pressure drop characteristics and to validate the reliability of measurement technology 32 …”

“…The calculation of pressure drop was performed with the following equation 33 :

\frac{dp}{dx} = {σk}_{p} u B^{2},

where k p = c /(1 + a /3 b + c ), c = t w σ w / σ w , σ and σ w are the electric conductivities of LiPb and wall in units of S/m; a and b are the lengths of the sides of the rectangular pipe in units of m; t is the thickness of wall in unit of m; u is the average velocity in unit of m/s; B is the magnetic field in unit of T. The experimental and calculated results are shown in Figure 13 32 …”

Summary The liquid lithium lead (LiPb) blanket concept has become a promising design for fusion reactor, for example, international thermonuclear experimental reactor (ITER) and the demonstration (DEMO) reactor. To promote the successful application of fusion energy, detailed studies on key issues of the LiPb blanket were performed, such as corrosion behavior, thermal hydraulics and coolant safety etc. Some experimental facilities needed for the key issue studies were designed and developed under the research program. The series LiPb experimental loops, named DRAGON, were developed in China, including the thermal convection loops DRAGON‐I/II/III and the multi‐functional experimental loop DRAGON‐IV. To perform the integrated experiments under the multi‐physical field conditions for DEMO blanket, a dual‐coolant thermal integrated experimental loop DRAGON‐V was built in 2017. It is a multi‐functional test platform for the research and development (R&D) of key issues of liquid LiPb blanket to provide the necessary database for ITER and DEMO. Up to now, a lot of experiments have been performed to investigate the LiPb technologies, such as corrosion behaviors of structural materials both with and without magnetic field, corrosion resistance technology, magneto‐hydrodynamics effect, and interaction between typical coolants during in‐box loss of coolant accident etc. The results will support the R&D of the key techniques and the engineering design for ITER test blanket module and further DEMO.

“…Several authors have compared predictions obtained with Equation ( 13) against the effective pressure gradients observed experimentally [46,[50][51][52][53][54][55][56]. An overview of the deviation between theoretical and averaged measured pressure coefficient k p is given in Table 5 and graphically presented in Figure 11.…”
