Knolls Atomic Power Laboratory (KAPL) is a research and development facility supporting the United States Naval Nuclear Propulsion Program. KAPL recently collaborated with Bettis Atomic Power Laboratory to test a supercritical carbon dioxide (S-CO2) Brayton power cycle system.
The system was designed to operate at high speed and high gas pressure, which means the turbine shaft bearings must withstand a wide range of radial and axial loads. The thrust bearings used to constrain the axial forces, however, showed extensive wear at certain speeds.
Using COMSOL Multiphysics, KAPL was able to analyze the structural mechanics, fluid mechanics, and heat transfer of the Brayton power cycle system to better understand the operation and deterioration of the thrust bearings. This allowed them to optimize geometry and to improve bearing performance.
