... bubble flows, experimental data on drag coefficient and interfacial area concentration have been obtained for air-water flows in a 2 × 1 rod channel simplifying a boiling water nuclear reactor fuel rod bundle. In order to know the effects of liquid properties on the data, the temperature of the test...

...Luis San Andrés; Dario Rubio; Tae Ho Kim Gas foil bearings (GFBs) satisfy the requirements for oil-free turbomachinery, i.e., simple construction and ensuring low drag friction and reliable high speed operation. However, GFBs have a limited load capacity and minimal damping, as well as frequency...
