Linear and Nonlinear Modelling of Gas Turbine Engines
… and shaft speeds of a Rolls Royce aircraft gas turbine. It is motivated by the desire to exploit recent advances in modelling linear and nonlinear systems and the need to investigate the suitability of various model representations in nonlinear gas turbine modelling.<br/><br/>The first part of …

Determining appropriate loss coefficients for use in the nozzle-model of a stage-by-stage turbine model
A previously developed turbine modelling methodology, requiring minimal blade passage information, produced a customizable turbine stage component. This stage-by-stage turbine nozzlemodel component was derived from the synthesis of classical turbine theory and classical nozzle theory enabling the …

Dynamic clearance modelling of steam turbines
… has become important to the field of steam turbine modelling. This study sought to develop a computationally inexpensive turbine model with minimal OEM intervention in order to predict the internal clearances of high-pressure and intermediate-pressure turbines from Eskom's current turbine …

Identification of linear and nonlinear systems using multisine signals with a gas turbine application
… of test signals for both linear and nonlinear modelling and their application to an engineering problem. It is motivated by a desire to fully exploit the recent advances in computer technology, which make the design and application of complex multisine test signals a practical possibility. The …

Comprehensive throughflow method for steam turbine development
… measurements. However, condensation in steam turbines is much more complex and optical measurements show a much broader droplet spectrum than in nozzles and steady cascade expansions. The dominant theory explaining this behaviour is that large-scale fluctuations in static temperature …
