Unsteady Combustor Physics Book Review:

Developing clean, sustainable energy systems is a pre-eminent issue of our time. Most projections indicate that combustion-based energy conversion systems will continue to be the predominant approach for the majority of our energy usage. Unsteady combustor issues present the key challenge associated with the development of clean, high-efficiency combustion systems such as those used for power generation, heating or propulsion applications. This comprehensive study is unique, treating the subject in a systematic manner. Although this book focuses on unsteady combusting flows, it places particular emphasis on the system dynamics that occur at the intersection of the combustion, fluid mechanics and acoustic disciplines. Individuals with a background in fluid mechanics and combustion will find this book to be an incomparable study that synthesises these fields into a coherent understanding of the intrinsically unsteady processes in combustors.

Swirling Flows and Flames Book Review:

Swirl flows are used in a wide range of industrial applications. In non-reacting cases, examples of applications include vortex amplifiers and reactors, heat exchangers, jet pumps, and cyclone separators. In reacting cases, swirlers are widely used in combustion systems, such as gas turbines, industrial furnaces, boilers, gasoline and diesel engines, and many other practical heating devices. Effects of using swirl on flow and combustion are significant and varied, and concern, for example, aerodynamics, mixing, flame stability, intensity of combustion, and pollutant emissions. The purpose of this book is to present recent research efforts to understand and characterize swirling flows of different types and in different applications. These include gaseous, liquid, and solid fuels in order to enhance combustion systems and their energy efficiency. Swirl flows are very complex and the studies proposed in this project are based on different means, including theoretical calculations, numerical modeling, and experimental measurements.

Forced Response of Swirl Stabilized Flames in Hydrogen Enriched Gas Turbines Book Review:

The forced response of swirl-stabilized lean-premixed turbulent flames to inlet velocity and/or equivalence ratio oscillations in hydrogen enriched laboratory-scale gas turbine combustors was experimentally investigated. To characterize the response of premixed and partially premixed flames, several measurement techniques were used. Inlet velocity and equivalence ratio fluctuations were measured by the two-microphone method and the infrared absorption technique, respectively. Global heat release oscillations were determined by measuring naturally occurring flame chemiluminescence emissions using photomultiplier tubes. Steady-state flame structure and phase-resolved flame dynamics were characterized by CH* chemiluminescence imaging using an intensified CCD camera. Results show that the response of a premixed flame to inlet velocity oscillations is strongly dependent on the effective flame length. This extends previous experimental and analytical results from laminar to turbulent premixed flames. The nonlinear response of the flame is manifested by shear layer rollup and unsteady flame liftoff, depending on the amplitude of perturbations. The response of hydrogen-enriched flames is linear, irrespective of vortex shedding. The forced response of a flame to equivalence ratio oscillations alone was achieved by using a fuel modulation method. When the flame is perturbed by mixture ratio modulations, it shows both linear and nonlinear responses. The nonlinearity is associated with the intrinsically nonlinear dependence of burning velocity and equivalence ratio upon the heat release. Finally, the response of a partially premixed flame to perturbations of both inlet velocity and equivalence ratio was studied. Unsteady local extinction events were identified as a mechanism of nonlinearity, which results from flame stretching effects. In particular, unsteady local extinction is more obvious in the nonlinear dynamics of hydrogen enriched partially premixed flames. The phase difference between inlet velocity and equivalence ratio nonuniformities is a key parameter controlling the linear and nonlinear response of a partially premixed flame. Results also show that in the linear regime, the response of a partially premixed flame can be reconstructed using the responses of a flame to velocity and equivalence ratio, using a vector summation rule.

Combustion Noise Book Review:

November, 2008 Anna Schwarz, Johannes Janicka In the last thirty years noise emission has developed into a topic of increasing importance to society and economy. In ?elds such as air, road and rail traf?c, the control of noise emissions and development of associated noise-reduction techno- gies is a central requirement for social acceptance and economical competitiveness. The noise emission of combustion systems is a major part of the task of noise - duction. The following aspects motivate research: • Modern combustion chambers in technical combustion systems with low pol- tion exhausts are 5 - 8 dB louder compared to their predecessors. In the ope- tional state the noise pressure levels achieved can even be 10-15 dB louder. • High capacity torches in the chemical industry are usually placed at ground level because of the reasons of noise emissions instead of being placed at a height suitable for safety and security. • For airplanes the combustion emissions become a more and more important topic. The combustion instability and noise issues are one major obstacle for the introduction of green technologies as lean fuel combustion and premixed burners in aero-engines. The direct and indirect contribution of combustion noise to the overall core noise is still under discussion. However, it is clear that the core noise besides the fan tone will become an important noise source in future aero-engine designs. To further reduce the jet noise, geared ultra high bypass ratio fans are driven by only a few highly loaded turbine stages.

Flashback Mechanisms in Lean Premixed Gas Turbine Combustion Book Review:

Blending fuels with hydrogen offers the potential to reduce NOx and CO2 emissions in gas turbines, but doing so introduces potential new problems such as flashback. Flashback can lead to thermal overload and destruction of hardware in the turbine engine, with potentially expensive consequences. The little research on flashback that is available is fragmented. Flashback Mechanisms in Lean Premixed Gas Turbine Combustion by Ali Cemal Benim will address not only the overall issue of the flashback phenomenon, but also the issue of fragmented and incomplete research. Presents a coherent review of flame flashback (a classic problem in premixed combustion) and its connection with the growing trend of popularity of more-efficient hydrogen-blend fuels Begins with a brief review of industrial gas turbine combustion technology Covers current environmental and economic motivations for replacing natural gas with hydrogen-blend fuels
