In the development of liquid metal Rankine cycle system, experiments using liquid metals generally cannot be conducted on the International Space Station (ISS) or the space shuttles due to a number of issues including safety. Some other fluids must be used to simulate potassium flows in a Rankine cycle. In this paper an analysis for the simulation using surrogate fluids is made. The results of the analysis indicate that single-phase liquid metal flows, either liquid or vapor, can be simulated using surrogate fluids both in ground and space experiments. For two-phase liquid-metal flow, a credible simulation with a surrogate fluid is currently not possible. For the problem of vapor-production efficiency in a boiler, a simulation using a surrogate fluid whose properties are similar to potassium is workable. A high concentration of copper nanoparticles in water (Cu-water nanofluid) is considered a potential possibility for a fluid to simulate liquid-metal turbulent flow and the boiling process. In the final stage of developing the liquid-metal Rankine-cycle system, experimental tests in a subscale liquid-metal system are still indispensable.

New data on critical holdups of dispersed phase were measured at which the phase inversion took place. The systems studied differed in the ratio of phase viscosities and interfacial tension. A weak dependence was found of critical holdups on the impeller revolutions and on the material contactor; on the contrary, a considerable effect of viscosity was found out as far as the viscosity of continuous phase exceeded that of dispersed phase.
