Supercritical Carbon Dioxide Power Cycles:
Turbomachinery Design Concepts for Various Applications

Join us Wednesday, May 27, 2020, at 12:00 p.m.–1:00 p.m. (U.S. Central Time)

Hosts: Jeff Moore, Ph.D. and Jason Wilkes, Ph.D.

Supercritical Carbon Dioxide (sCO2) power cycles offer high efficiency and power density relative to the incumbent Steam Rankine and Air Brayton cycles for power generation. One significant advantage of sCO2 cycles over other Brayton cycles is that the high fluid density results in very compact turbomachinery for compression and expansion. However, the combination of pressure, temperature, and density in sCO2 power cycles is outside the experience base of existing turbomachines such as gas turbines, steam turbines, and even high-pressure gas compressors making sCO2 turbomachinery design a significant challenge for realizing these cycles.

This webinar helps frame the resulting operating requirements and design concepts for the pumps, compressors, and expanders required for various cycle configurations. The webinar covers the most common challenges to sCO2 turbomachines including rotordynamics, pressure containment, sealing, and transient/off-design operation. Additional challenges including thermal management, over speed risk, aerodynamic performance, and range requirements will also be covered.
