Abstract
  • A one-sixth scaled facility was constructed at Oregon State University to determine the pressure losses around Westinghouse's AP1000 Passive Containment Cooling System. An explanation of the AP1000 Passive Containment Cooling System is given. This study examined the pressure loss and loss coefficient around the 180 degree turn of the Passive Containment Cooling System. Computational Fluid Dynamics Models were developed for multiple turning vane designs. Comparisons were made between the FLUENT models and the experimental facility. A turning vane reduced the pressure loss by at least a factor of four compared to a straight geometry. The pressure loss around the 180 degree turn was insignificant compared to the pressure loss encountered in other locations in the Passive Containment Cooling System. The Computational Fluid Dynamics code accurately predicted the ow behavior around the 180 degree turn. All of the ow tests were performed under turbulent conditions.
