Abstract: Abstract. Industrial gas turbines play a fundamental role in modern energy infrastructure, serving as key enablers of reliable power generation and industrial operations. With rising global energy demand and the imperative ...

Abstract: This paper describes the development of a new throughflow method for the analysis of axial multistage turbines with cooling by air from compressor bleed. The method is based on a stream function approach and a finite element ...

Abstract: This paper describes a methodology and a fully tested and calibrated mathematical model for the treatment of endwall effects in axial compressor aerodynamic calculations. Additional losses and deviations caused by the ...

Abstract: This paper describes a new universal algebraic model for the estimation of flow deflection and losses in axial compressor inlet guide vane devices. The model deals with nominal flow and faroffdesign operating conditions ...

Abstract: In the published paper, the expressions listed under (51) were miswritten. The correct version is (51)–for a rotor:–for a stator:(w2/w1)T<Ctc(WRmin)T/1.3(w2/w1)A<(WRmin)A(w2/w1)H<(WRmin)H/1.3(w2/w1)T<(WRmin)T ...

Abstract: Abstract. The thermal load on the endwalls of the hot gas path of gas turbines, in particular those of the nozzle guide vanes (NGVs), has increased considerably over the last few decades, both because of the common premixed ...

Abstract: Abstract. Gas turbines have advanced significantly in recent years, particularly in compressor and turbine efficiency, because of aerodynamic breakthroughs based on numerical flow simulations. Additionally, modern energy ...

Abstract: As a consequence of the increasing share of volatile renewable energy sources such as wind and solar in present-day electrical grid systems, time variations of the power demand for fossil fuel plants can become more sudden. ...
