Book Description
Recent advances in microfabrication technologies have enabled the development of entirely new classes of small-scale devices with applications in fields ranging from biomedicine, to wireless communication and computing, to reconnaissance, and to augmentation of human function. In many cases, however, what these devices can actually accomplish is limited by the low energy density of their energy storage and conversion systems. This breakthrough book brings together in one place the information necessary to develop the high energy density combustion-based power sources that will enable many of these devices to realize their full potential. Engineers and scientists working in energy-related fields will find: • An overview of the fundamental physics and phenomena of microscale combustion; • Presentations of the latest modeling and simulation techniques for gasphase and catalytic micro-reactors; • The latest results from experiments in small-scale liquid film, microtube, and porous combustors, micro-thrusters, and micro heat engines; • An assessment of the additional research necessary to develop compact and high energy density energy conversion systems that are truly practical.

Book Description
As part of the MIT micro-gas turbine engine project, the development of a hydrocarbon-fueled catalytic micro-combustion system is presented. A conventionally-machined catalytic flow reactor was built to simulate the micro-combustor and to better understand the catalytic combustion at micro-scale. In the conventionally-machined catalytic flow reactor, catalytic propane/air combustion was achieved over platinum. A 3-D finite element heat transfer model was also developed to assess the heat transfer characteristics of the catalytic micro-combustor. It has been concluded that catalytic combustion in the micro-combustor is limited by diffusion of fuel into the catalyst surface. To address this issue, a catalytic structure with larger surface area was suggested and tested. It was shown that the larger surface area catalyst increased the chemical efficiency. Design guidelines for the next generation catalytic micro-combustor are presented as well.

Book Description
Keeping up with the rapid growing technology and meeting its power demands, compact and portable devices are desired. Electrochemical batteries currently satisfy these standards. However, micro-combustion has advantages over lithium-ion batteries. Micro-combustion can produce a higher power density, higher heat and mass transfer coefficients, as well as shorter recharge duration. Utilizing hydrocarbons as a fuel in micro-combustion could lead to the possibility of applying this technology towards aerospace and/or defense. The reduction in size and its components would greatly benefit areas of weight and cost. With the decrease in size of micro-combustion offers a larger surface-to-volume ratio but also leads to flame quenching and short residence time. Sustaining combustion requires additional methods such as heat-recirculation and porous inert media. Micro-combustor design with a total volume of 1188 mm3 was validated. Mass flow rate of premixed fuel/air entered the system at an axial velocity of 2.0 m/s. This design was set forth with power production of 100 Watts. Computational fluid dynamic studies with ANSYS 13.0 Workbench help simulate the fluid flow in the proposed models. The numerical methods and algorithm calculated fluid dynamics and heat transfer. By varying the inner annulus wall to converge, power increase as much 13% was simulated. The pressure, temperature, and velocity also increased as the heat loss of the total system decreased by sixth of a fraction. With the variants of the angle draft annulus wall creating a compressor affect could lead to further research to be applied to aerospace and defense technologies.

Book Description
Combustion Technology: Some Modern Developments reviews modern developments in combustion technology, with emphasis on furnace flames. Topics covered range from equilibria and chemical kinetics in flames to corrosion and deposits in combustion systems, along with combustion aerodynamics and noise. Heat transfer from non-luminous flames in furnaces is also investigated. Comprised of 15 chapters, this book begins with an overview of some aspects of the chemistry of flames, followed by a discussion on the problem of corrosion and deposits. Subsequent chapters focus on aerodynamics and heat transfer in combustors, together with combustion noise and the application of aerodynamic principles to flame stabilization in high-speed flow; radiative heat transfer in combustion chambers; electrical properties of flames; flame-field interactions and their practical applications; generation of electricity by magnetohydrodynamic methods; and practical aspects of magnetohydrodynamic power generation. The book also assesses the influence of stirred reactor theory on design principles for high-performance combustion chambers and concludes with a summary of developments in the design and utilization of oil burners. This monograph should be of interest to engineers and combustion technologists.

Book Description
Small and micro combined heat and power (CHP) systems are a form of cogeneration technology suitable for domestic and community buildings, commercial establishments and industrial facilities, as well as local heat networks. One of the benefits of using cogeneration plant is a vastly improved energy efficiency: in some cases achieving up to 80–90% systems efficiency, whereas small-scale electricity production is typically at well below 40% efficiency, using the same amount of fuel. This higher efficiency affords users greater energy security and increased long-term sustainability of energy resources, while lower overall emissions levels also contribute to an improved environmental performance. Small and micro combined heat and power (CHP) systems provides a systematic and comprehensive review of the technological and practical developments of small and micro CHP systems. Part one opens with reviews of small and micro CHP systems and their techno-economic and performance assessment, as well as their integration into distributed energy systems and their increasing utilisation of biomass fuels. Part two focuses on the development of different types of CHP technology, including internal combustion and reciprocating engines, gas turbines and microturbines, Stirling engines, organic Rankine cycle process and fuel cell systems. Heat-activated cooling (i.e. trigeneration) technologies and energy storage systems, of importance to the regional/seasonal viability of this technology round out this section. Finally, part three covers the range of applications of small and micro CHP systems, from residential buildings and district heating, to commercial buildings and industrial applications, as well as reviewing the market deployment of this important technology. With its distinguished editor and international team of expert contributors, Small and micro combined heat and power (CHP) systems is an essential reference work for anyone involved or interested in the design, development, installation and optimisation of small and micro CHP systems. Reviews small- and micro-CHP systems and their techno-economic and performance assessment Explores integration into distributed energy systems and their increasing utilisation of biomass fuels Focuses on the development of different types of CHP technology, including internal combustion and reciprocating engines
