“…In Z-pinch IFE there are essentially three configurations of protection that need to be addressed: a conical top plug containing flibe shields the top, flowing liquid layers protecting the side walls, and a two-phase (bubbling) pool at the bottom of the chamber. Studies concerning the flowing liquid layers in shock tube experiments verified that several layers separated with a void significantly reduce the wall loading [32], and there may exist an optimum void-space-toliquid-thickness ratio to minimize the impulse force and reduce the liquid sheet break-up. Work is ongoing to study and model the shock attenuation and energy absorption in solid foam layers and in two-phase pools for the upper and lower protection schemes proposed in Z-pinch reactor designs.…”

“…so as to have parallel walls to perform flow visualization anywhere along the tube~e.g., Ref. 60!. The facility's structural capability allows for the production of Mach-5 shock waves in air at atmospheric pressure.…”
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
