Book excerpt: This paper presents the performance cycle analysis of a dual-spool, separate-exhaust turbofan engine, with an Interstage Turbine Burner serving as a secondary combustor. The ITB, which is located at the transition duct between the high- and the low-pressure turbines, is a relatively new concept for increasing specific thrust and lowering pollutant emissions in modern jet engine propulsion. A detailed performance analysis of this engine has been conducted for steady-state engine performance prediction. A code is written and is capable of predicting engine performances (i.e., thrust and thrust specific fuel consumption) at varying flight conditions and throttle settings. Two design-point engines were studied to reveal trends in performance at both full and partial throttle operations. A mission analysis is also presented to assure the advantage of saving fuel by adding ITB.Liew, K. H. and Urip, E. and Yang, S. L. and Mattingly, J. D. and Marek, C.

This book was released on 2018-06-03 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report presents the performance of a steady-state, dual-spool, separate-exhaust turbofan engine, with an interstage turbine burner (ITB) serving as a secondary combustor. The ITB, which is located in the transition duct between the high- and the low-pressure turbines, is a relatively new concept for increasing specific thrust and lowering pollutant emissions in modern jet-engine propulsion. A detailed off-design performance analysis of ITB engines is written in Microsoft(Registered Trademark) Excel (Redmond, Washington) macrocode with Visual Basic Application to calculate engine performances over the entire operating envelope. Several design-point engine cases are pre-selected using a parametric cycle-analysis code developed previously in Microsoft(Registered Trademark) Excel, for off-design analysis. The off-design code calculates engine performances (i.e. thrust and thrust-specific-fuel-consumption) at various flight conditions and throttle settings.Liew, K. H. and Urip, E. and Yang, S.

This book was released on 2013-07 with total page 22 pages. Available in PDF, EPUB and Kindle. Book excerpt: Today's modern aircraft is based on air-breathing jet propulsion systems, which use moving fluids as substances to transform energy carried by the fluids into power. Throughout aero-vehicle evolution, improvements have been made to the engine efficiency and pollutants reduction. This study focuses on a parametric cycle analysis of a dual-spool, separate-flow turbofan engine with an Interstage Turbine Burner (ITB). The ITB considered in this paper is a relatively new concept in modern jet engine propulsion. The JTB serves as a secondary combustor and is located between the high- and the low-pressure turbine, i.e., the transition duct. The objective of this study is to use design parameters, such as flight Mach number, compressor pressure ratio, fan pressure ratio, fan bypass ratio, linear relation between high- and low-pressure turbines, and high-pressure turbine inlet temperature to obtain engine performance parameters, such as specific thrust and thrust specific fuel consumption. Results of this study can provide guidance in identifying the performance characteristics of various engine components, which can then be used to develop, analyze, integrate, and optimize the system performance of turbofan engines with an ITB.

Book Synopsis Modern Gas Turbine Systems by : Peter Jansohn
Download or read book Modern Gas Turbine Systems written by Peter Jansohn and published by Elsevier. This book was released on 2013-08-31 with total page 849 pages. Available in PDF, EPUB and Kindle. Book excerpt: Modern gas turbine power plants represent one of the most efficient and economic conventional power generation technologies suitable for large-scale and smaller scale applications. Alongside this, gas turbine systems operate with low emissions and are more flexible in their operational characteristics than other large-scale generation units such as steam cycle plants. Gas turbines are unrivalled in their superior power density (power-to-weight) and are thus the prime choice for industrial applications where size and weight matter the most. Developments in the field look to improve on this performance, aiming at higher efficiency generation, lower emission systems and more fuel-flexible operation to utilise lower-grade gases, liquid fuels, and gasified solid fuels/biomass. Modern gas turbine systems provides a comprehensive review of gas turbine science and engineering. The first part of the book provides an overview of gas turbine types, applications and cycles. Part two moves on to explore major components of modern gas turbine systems including compressors, combustors and turbogenerators.

Book Synopsis Small-Scale Energy Systems with Gas Turbines and Heat Pumps by : Satoru Okamoto
Download or read book Small-Scale Energy Systems with Gas Turbines and Heat Pumps written by Satoru Okamoto and published by MDPI. This book was released on 2021-03-29 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: A heat pump system can produce an amount of heat energy that is greater than the amount of energy used to run the heat pump system. Thus, a heat pump system is considered to be a machine system that can use energies efficiently, as is the load leveling air-conditioning system utilizing unutilized energies at high levels. Adaptations of gas turbines for industrial, utility, and marine-propulsion applications have long been accepted as means for generating power with high efficiency and ease of maintenance. Cogeneration with gas turbine is frequently defined as the sequential production of useful thermal energy and shaft power from a single energy source. For applications that generate electricity, the power can either be used internally or supplied to the utility grid. This Special Issue intends to provide an overviews of the existing knowledge related with various aspects of “Small-Scale Energy Systems with Gas Turbines and Heat Pumps”, and contributions on, but not limited to the following subjects were encouraged: wake of stator vane to improve sealing effectiveness; gas turbine cycle with external combustion chamber for prosumer and distributed energy systems; computational simulation of gas turbine engine operating with different blends of biodiesel; experimental methodology and facility for the engine performance and emissions evaluation using jet and biodiesel blends; experimental analysis of an air heat pump for heating service; hybrid fuel cell-Brayton cycle for combined heat and power; design analysis of micro gas turbines in closed cycles. Seven papers were published in the Special Issue out of a total of 12 submitted.
Book Synopsis Gas Turbine Parameter Corrections by : Allan J. Volponi
Download or read book Gas Turbine Parameter Corrections written by Allan J. Volponi and published by Springer Nature. This book was released on 2020-02-29 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume provides an exhaustive catalog of common standard day corrections for gas turbine gas path parameters, explores their history, and, most importantly, provides a mathematical framework for the derivation of these important normalization factors. Although use of these corrections is common practice within industry, government, and academia, their genesis, and, in particular, how they can be derived from simple principles, is not general knowledge among many of those who use them on a regular basis. This book elucidates calculation of these important coefficients. Standing as a one-stop source on derivations and a methodology for additional parameter correction refinements, Gas Turbine Parameter Corrections, is ideal as a desk reference for practitioners and researchers, as well as supplemental instruction for university courses on gas turbine performance, control, and DPHM (diagnostics, prognostics and health management).
Book Synopsis Cycle Analysis and Heat Transfer Estimation of a Thermochemical Recuperative Turbofan Engine with Multistage Blade Intercooling by : George Danny Herrera
Download or read book Cycle Analysis and Heat Transfer Estimation of a Thermochemical Recuperative Turbofan Engine with Multistage Blade Intercooling written by George Danny Herrera and published by . This book was released on 2019 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Improvements in the aeronautical industry continue to advance despite its slow progress. When it comes to improving the overall efficiency and exhaust emissions of a typical turbofan engine, focus is put on increasing compressor pressure ratio, increasing turbine inlet temperature, and improving combustion techniques. However, there are fundamental thermodynamic modifications and fuel enhancement techniques that can significantly improve the jet engine that have not yet been implemented. This paper introduces the concept of a fuel-integrated energy recuperative (i.e. thermochemical recuperative) aero-derivative (FIERA) gas turbine engine with a multistage blade intercooler and exhaust heat recuperator. The FIERA concept aims to transfer energy into the fuel to spur endothermic reactions causing the fuel to decompose into higher caloric gases. By using the fuel as a heat sink through intercooling and waste heat recuperation, lower back work and better combustion can be achieved. This can correlate to higher efficiencies, lower fuel consumption, and improved emissions. In this work, an on-design cycle analysis was done on a steady-state, dual-spool, separate-exhaust turbofan engine with FIERA, to investigate how the engine performance parameters vary with changes in the flight conditions, design limits, and design choices. The multistage compressor was modeled using a repeating-stage, repeating-row, and mean-line design approach to estimate compressor performance and total blade surface area. This was necessary to estimate the heat transfer rates for the blade intercoolers using the effectiveness-NTU (Number of Transfer Units) method and Nusselt-Reynold-Prandtl number correlations. The study compares a baseline design without FIERA to variations of the FIERA concept in order to observe its benefits and drawbacks.
