Liquid metal fuels are being employed as Rankine cycle heat sources for undersea vehicle propulsion systems, necessitating investigation of the fundamental chemical, thermodynamics, and hydrodynamic processes which occur during the confined combustion of these fuels. Results of the development of techniques for the use of flash X-ray radiography to investigate these processes is presented. Experimental combustors designed to permit studies of the combustion zone and fluid dynamics of the jet-driven circulating flow in the fuel bath are described. Radiographic images showing the reaction zone, multiphase flow structures and the behavior and mixing characteristics of the products-rich phase are shown, demonstrating the utility of this experimental technique in energy conversion research.
