This book was released on 2009 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The research study focuses on the idea of simulation of an Integrated FullElectric Propulsion System. The simulation required the development of a gasturbine performance model that could predict the dynamic behaviour of theengine in response to a fluctuation of electrical load. For this purposes it wasnecessary to evaluate the thermodynamic working process of the gas turbineand a computer code was created. A design point model written in FORTRAN77 had been transformed to predict the steady state and transientperformance of a two-shaft gas turbine and single shaft gas turbine. Themodels were based on the thermodynamic law of conservation of mass. Forthe model of the two-shaft gas turbine controls system equations had beenderived from off-design analysis and implemented as handles for operation. Both the models were then transformed to a direct link library for theSIMULINK? package. They were further implemented with an electricalnetwork model to form a high-fidelity prime mover-electrical networkpropulsiondrive interface with which a complete systems analysis was doneto understand the response of the three systems in parallel. In a second part heat exchanger modelling had to be performed so as tocreate a gas turbine model of an intercooled-recuperated engine. This wasdone for the steady state behaviour and sizing problem of heat exchangers. The models were run parallel to the steady state code as a validationexercise. Due to time and project restraints the complete incorporation of themodels with the gas turbine code was not performed and only a uni-directionalsystem of heat exchanger was created. Over all the period of researchparametric studies had been done for comparison of various aspects ofperformance. The high fidelity model of the prime mover-electrical network highlighted thereasons for studying the impact of the propulsion drive and electrical networkload dynamics on the operation of the prime movers and vice versa. The loss-of-propulsion-load scenario case study has demonstrated the capabilities ofthe integrated model, showing clear interactions between the individualsubsystems. The interface can now be used to analyse novel types of gasturbine engines in the future. The method adopted to simulate transientperformance of gas turbines was useful in understanding the impact of bleedair on current and novel cycles. Finally the task of heat exchanger simulationemphasized the need to create better and accurate models to understand theimpact of its behaviour on the gas turbine.

Available in PDF, EPUB and Kindle. Book excerpt: The process of gas turbine development requires different mathematical models. In particular, physics-based nonlinear dynamic models are widely used in the development of control and diagnostic systems. The present chapter firstly reviews known works on nonlinear dynamic engine modeling centering on model applications and developments. As an important development, modeling of heating up engine components is considered. This phenomenon consists in a radial clearance change during transients that influences engine static and dynamic performances. This clearance change is usually computed by a finite element method that is critical to computer resources. The chapter secondly presents a new and more rapid simulation methodology to integrate two dynamic processes, a general engine transient and a clearance change. This allows creating a more accurate and relatively fast engine dynamic model that is easy to use in the design of control and diagnostic systems. Finally, the chapter introduces further methodology enhancement consisting in the consideration of the influence of varying metal temperature on the strains induced by mechanical loads. To validate methodology, it is applied to a particular turbofan engine, and the simulated and real engine dynamic performances are compared.

Book excerpt: Industrial Gas Turbines: Performance and Operability explains important aspects of gas turbine performance such as performance deterioration, service life and engine emissions. Traditionally, gas turbine performance has been taught from a design perspective with insufficient attention paid to the operational issues of a specific site. Operators are not always sufficiently familiar with engine performance issues to resolve operational problems and optimise performance.Industrial Gas Turbines: Performance and Operability discusses the key factors determining the performance of compressors, turbines, combustion and engine controls. An accompanying engine simulator CD illustrates gas turbine performance from the perspective of the operator, building on the concepts discussed in the text. The simulator is effectively a virtual engine and can be subjected to operating conditions that would be dangerous and damaging to an engine in real-life conditions. It also deals with issues of engine deterioration, emissions and turbine life. The combined use of text and simulators is designed to allow the reader to better understand and optimise gas turbine operation. Discusses the key factors in determining the perfomance of compressors, turbines, combustion and engine controls Explains important aspects of gas and turbine perfomance such as service life and engine emissions Accompanied by CD illustrating gas turbine performance, building on the concepts discussed in the text

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This SAE Aerospace Information Report (AIR) provides a review of real-time modeling methodologies for gas turbine engine performance. The application of real-time models and modeling methodologies are discussed. The modeling methodologies addressed in this AIR concentrate on the aerothermal portion of the gas turbine propulsion system. Characteristics of the models, the various algorithms used in them, and system integration issues are also reviewed. In addition, example cases of digital models in source code are provided for several methodologies. This document has been updated to include an advancement in aerothermodynamic real time model transient simulation methodology. In recent years, there has been an emphasis on using a single model for both non-real-time and real-time simulation, without any loss in accuracy and without the extra software maintenance efforts associated with having a separate real-time model. Discussion of a method to optimize the equation structure of the non-real-time aerothermal model for real-time execution is included.

This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The gas turbine which has found numerous applications in Air, Land and Seaapplications, as a propulsion system, electricity generator and prime mover, issubject to deterioration of its individual components. In the past, variousmethodologies have been developed to quantify this deterioration with varyingdegrees of success. No single method addresses all issues pertaining to gasturbine diagnostics and thus, room for improvement exists. The first part of thisresearch investigates the feasibility of non-linear W eighted Least Squares as agas turbine component deterioration quantification tool. Two new weightingschemes have been developed to address measurement noise. Four caseshave been run to demonstrate the non-linear weighted least squares method, inconjunction with the new weighting schemes. Results demonstrate that thenon-linear weighted least squares method effectively addresses measurementnoise and quantifies gas path component faults with improved accuracy over itslinear counterpart and over methods that do not address measurement noise. Since Gas turbine diagnostics is based on analysis of engine performance atgiven ambient and power setting conditions; accurate and reliable engineperformance modelling and simulation models are essential for meaningful gasturbine diagnostics. The second part of this research therefore sought todevelop a multi-fuel and multi-caloric simulation method with the view ofimproving simulation accuracy. The method developed is based on non-linearinterpolation of fuel tables. Fuel tables for Jet-A, UK Natural gas, Kerosene andDiesel were produced. Six case studies were carried out and the resultsdemonstrate that the method has significantly improved accuracy over linearinterpolation based methods and methods that assume thermal perfection.
