...Jing-Lun Fu; Jian-Jun Liu; Si-Jing Zhou The exhaust system in condensing steam turbines is used to recover leaving kinetic energy of the last stage turbine, while guiding the flow from turbine to condenser. The flows in the exhaust system and the turbine stage are fully coupled and inherently...

...Filippo Rubechini; Andrea Schneider; Andrea Arnone; Stefano Cecchi; Francesco Malavasi A three-dimensional Reynolds averaged Navier–Stokes solver was applied to the aerodynamic redesigning of a 17-stage steam turbine. The redesign procedure was divided into three steps. In the first one, a single...

... on both inside and outside the passage. The study involves both straight and annular cascades mounting a typical intermediate reaction degree section, designed for steam turbines. Blades are built by stacking the same 2D profile along different linear axes, characterized by different angles with respect...

...Krzysztof Kosowski; Karol Tucki; Adrian Kosowski We present the results of numerical tests of artificial neural networks (ANNs) applied in the investigations of flows in steam turbine cascades. Typical constant cross-sectional blades, as well as high-performance blades, were both considered...

...Tim Rice; David Bell; Gurnam Singh The introduction of longer last stage blading in steam turbine power plant offers significant economic and environmental benefits. The modern trend, adopted by most leading steam turbine manufacturers, is to develop long last stage moving blades (LSMBs...

...Bo Song; Wing F. Ng; Joseph A. Cotroneo; Douglas C. Hofer; Gunnar Siden Three sets of low solidity steam turbine nozzle cascades were designed and tested. The objective was to reduce cost through a reduction in parts count while maintaining or improving performance. The primary application...

...V. S. P. Chaluvadi; A. I. Kalfas; H. P. Hodson; H. Ohyama; E. Watanabe This paper presents a study of the three-dimensional flow field within the blade rows of a high-pressure axial flow steam turbine stage. Compound lean angles have been employed to achieve relatively low blade loading for hub...
