Abstract : The thermo-hydraulic and fluid flow characteristics of a confined two-phase, two-component vortex were investigated both experimentally and analytically. The solid components of the two-phase mixtures that were studied were stainless steel microspheres and naturally enriched uranium dioxide spheroidized particles. The fluid component of the gas-solid vortex was either air or helium gas. An experimental apparatus was designed, fabricated, and operated to provide data on the effects of heat release from suspended particles on the fluid dynamics of a two-phase vortex chamber that simulated a colloid-core nuclear reactor. The apparatus was initially operated in the laboratory to provide baseline nonheated data and subsequently was located in a test cell of the Battelle Research Reactor to provide fission heating in the uranium dioxide particles.
