The influence of various optimization algorithms on nuclear power plant steam turbine exergy efficiency and destruction [PDF]
arXiv, 2021 This paper presents an exergy analysis of the whole turbine, turbine cylinders and cylinder parts in four different operating regimes. Analyzed turbine operates in nuclear power plant while three of four operating regimes are obtained by using optimization algorithms - SA (Simplex Algorithm), GA (Genetic Algorithm) and IGSA (Improved Genetic-Simplex ...

A New Steam Turbine Model for Utility System Design and Optimization
Chemical Engineering Transactions, 2014 Steam turbine shaft power performance and efficiencies depend on turbine size, type, and operating conditions. This work develops a new turbine performance model based on thermodynamic principles and semi-empirical equations to obtain general steam ...

Steam Degradation of Ytterbium Disilicate Environmental Barrier Coatings: Effect of Composition, Microstructure and Temperature [PDF]
arXiv, 2021 Recession of environmental barrier coatings (EBC) in environments containing steam is a pressing concern that requires further research before their implementation in gas turbine engines can be realized. In this work, free-standing plasma sprayed Yb2Si2O7 coatings were exposed to flowing steam at 1350 {\deg}C and 1400 {\deg}C for 96 h.

A Review on Environmental Barrier Coatings: History, Current State of the Art and Future Developments [PDF]
, 2020 The increasing demand for more efficient and environmental-friendly gas turbines has driven the development of new strategies for material development. SiC/SiC ceramic matrix composites (CMCs) can fulfil the stringent requirements; however, they require protection from the operating environment and debris ingested during operation.
