- W101706066 abstract "A recently developed heat transfer correlation can help determine acceptable water temperatures during a severe overcooling of the reactor vessel downcomer. This study contributes to an ongoing effort to prevent thermally induced cracking in reactor vessels. Thermally induced cracking develops when cold water suddenly contacts hot metal walls. This phenomenon could occur during certain PWR transients. Following an extensive literature survey, investigators built an experimental test facility to simulate the heat transfer phenomena found in a PWR reactor downcomer. The facility design emphasized reproducing the horizontal and vertical aspect ratios and the correct flow boundary conditions. The investigators selected Freon 113 as a working fluid to attain correct buoyancy forces with minimal wall heating. They then used the facility to test several inlet flows and temperature distributions using a wide range of Prandtl, Reynolds, and Grashof numbers. Thermocouples distributed at various elevations and distances from the walls measured heat fluxes and temperature profiles. The experimental observations allowed a detailed analysis of turbulent flow in the downcomer, from which the team developed a theoretical model of the heat transfer mechanisms. Surface renewal theory provided a starting point for the theoretical investigation. The key product of this study is a heat transfermore » correlation that accurately represents the impact of the parameters. This correlation fits the experimental data within 7% over Prandtl, Reynolds, and Grashof numbers spanning the thermal-hydraulic conditions commonly found in PWRs. 35 refs., 31 figs.« less" @default.
