Measurement of diffusion coefficient of liquid metals by using gradient heating furnace in ISS
The experimental techniques for the measurements of diffusion coefficient have been studied in JAXA toward the utilization of microgravity environment in ISS (International Space Station). The experimental cartridge for the Gradient Heating Furnace, GHF, was developed for the application of shear cell which is the advanced technique of diffusion experiments. The temperature profiles of GHF were measured for the diffusion experiments and the isothermal condition can be attained by the optimization of furnaces positions and temperatures.
