Through-flow analysis of air-cooled gas turbines
(Proceedings of the ASME Turbo Expo, 2012)
This paper describes the development of a new through-flow 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 ...
Off-design flow analysis and performance prediction of axial turbines
(American Society of Mechanical Engineers (ASME), 1997)
Through-flow methods for calculations in axial flow turbines are limited by two facts: They cannot handle local flow reversal, and loss prediction at off-design operating conditions is not sufficiently accurate. An attempt ...
Optimization of multista ge turbinesusing a through-flow code
(American Society of Mechanical Engineers (ASME), 2000)
Very fast and accurate flow calculation and performance pre-diction of multistage axial flow turbines at design and o-design conditions was perfo rmed using a compressible steady state in-viscid through-ow code with high ...
Laser insight into the turbulent swirl flow behind the axial flow fan
(American Society of Mechanical Engineers (ASME), 2014)
Complex experimental study of the turbulent swirl flow behind the axial fan is reported in this paper. Axial fan with nine blades, designed to generate Rankine vortex, was positioned in the circular pipe entrance transparent ...
Fully coupled through-flow method for industrial gas turbine analysis
(American Society of Mechanical Engineers (ASME), 2015)
A fully coupled method for calculation of the entire flow in single- and twin-shaft industrial gas turbines is described. It is based on individual through-flow methods for axial compressors and air-cooled gas turbines ...
Multistage axial compressor flow field predictions using CFD and throughflow calculations
(American Society of Mechanical Engineers (ASME), 2016)
A comparison between two different methods for aerodynamic calculation of multistage axial compressors is presented. Results obtained using classical 2D through-flow calculations were compared with CFD results for several ...
Modelling the transient behaviour of gas turbines
(American Society of Mechanical Engineers (ASME), 2019)
As a consequence of the increasing share of renewable energy sources in present-day electrical grid systems, time variations of the power demand for fossil fuel plants can become more sudden. Therefore, an ability to respond ...
Development of method and computer program for multistage axial compressor design: part I - mean line design and example cases
(American Society of Mechanical Engineers (ASME), 2018)
An axial compressor loss and deviation model that was developed and presented during previous research has now been used to develop a computer program for multistage compressor design. A set of input data including overall ...
A Comprehensive Analytical Shock Loss Model for Axial Compressor Cascades
(American Society of Mechanical Engineers (ASME), 2021)
The approach applied in various research papers that model compressor shock losses is valid only for certain types of airfoil cascades operating in a narrow range of working conditions. Lately, more general shock loss ...
Development of method and computer program for multistage axial compressor design: part II - two-dimensional design and validation using cfd
(American Society of Mechanical Engineers (ASME), 2018)
Part I of this paper presents a method and a computer program for the mean design of multistage axial compressors. This second part describes a method and an additional computer routine that use the basic mean line design ...
