A liquid metal flume for free surface magnetohydrodynamic experiments.
We present an experiment designed to study magnetohydrodynamic effects in free surface channel flow. The wide aspect ratio channel (the width to height ratio is about 15) is completely enclosed in an inert atmosphere to prevent oxidization of the liquid metal. A custom-designed pump reduces entrainment of oxygen, which was found to be a problem with standard centrifugal and gear pumps. Laser Do...
متن کاملRegulation by iron: RNA rules the rust.
Obtaining and maintaining proper levels of iron are major challenges for most organisms (reviews may be found in references 2, 9, and 10). The redox features that make iron such a versatile and valuable cofactor can also lead to formation of extremely toxic and highly reactive oxygen species, particularly the hydroxyl radical, which can damage any cellular component. Hence, bacteria and other o...
متن کاملThermal surface free energy and stress of iron
Absolute values of surface energy and surface stress of solids are hardly accessible by experiment. Here, we investigate the temperature dependence of both parameters for the (001) and (110) surface facets of body-centered cubic Fe from first-principles modeling taking into account vibrational, electronic, and magnetic degrees of freedom. The monotonic decrease of the surface energies of both f...
متن کاملModeling infinite/axisymmetric liquid metal magnetohydrodynamic free surface flows
Over the past several years, as part of the Advanced Power Extraction (APEX) project, liquid metal magnetohydrodynamic (MHD) film and jet flows have been modeled using the assumption of axisymmetry to simplify the governing equations to a more tractable two-dimensional (2D) form. The results of these 2D simulations as they pertain to liquid wall and divertor flows is presented here. The effect ...
متن کاملFree surface stability of liquid metal plasma facing components
An outstanding concern raised over the implementation of liquid metal plasma facing components in fusion reactors is the potential for ejection of liquid metal into the fusion plasma. The influences of Rayleigh–Taylor-like and Kelvin–Helmholtz-like instabilities were experimentally observed and quantified on the thermoelectric-driven liquid-metal plasmafacing structures (TELS) chamber at the Un...
