RISDevelopment of a Computational Tool to Simulate Foil Bearings for Supercritical CO2 Cycles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The foil bearing is an enabling technology for turbomachinery systems, which has the potential to enable cost efficient supercritical CO2 cycles. The direct use of the cycle's working fluid within the bearings results in ...
Effect of Operating Conditions on the Elastohydrodynamic Performance of Foil Thrust Bearings for Supercritical CO2 Cycles
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, a quasi-three-dimensional fluid–structure model using computational fluid dynamics for the fluid phase is presented to study the elastohydrodynamic performance of foil thrust bearings for supercritical CO2 ...
A Limited Role for Unforced Internal Variability in Twentieth-Century Warming
Publisher: American Meteorological Society
Abstract: AbstractThe early twentieth-century warming (EW; 1910?45) and the mid-twentieth-century cooling (MC; 1950?80) have been linked to both internal variability of the climate system and changes in external radiative forcing. ...
