...Shrey Sahai Gupta; Pramod Kumar Supercritical carbon dioxide (sCO 2 ) cycles are gaining attention for their efficiency and low carbon footprint in power plants. This study focuses on optimizing the performance of a 5 MW simple recuperated sCO 2 Brayton loop during inventory control, a recommended...

... comprising the primary flow path components—inducers, impellers, and volutes, and a realizable pump hardware that includes hub, shroud, and power unit cavities. Performance metrics, including head changes and efficiencies, are extracted both at a component and system level. Leakage flow rates of 27.6% and up...

..., and a sensitivity analysis is performed to understand the impact of cycle loss parameters and turbine cooling technology. Results were analyzed at the optimistic and realistic PGC loss scenarios. For the PGC open cycle, with optimistic combustor losses, efficiency was higher than Joule at all operating conditions...

...S. Can Gülen; Martin Curtis Modern heavy duty industrial gas turbines in combined cycle configuration, with rated efficiencies (at ISO base load) above 60% net LHV, are expected to play a significant role in reducing the carbon footprint of utility scale electricity generation. Even without...

... advanced combustion technologies, capable of elevated peak cylinder pressures and thermal efficiencies, thermal barrier coatings, exhaust waste heat recovery via SuperTurbo™ turbocompounding, and hybrid energy assisting and recovery through both mechanical and electrical systems. Following the concept...
