Book Synopsis Development of a Catalytic Combustion System for the MIT Micro Gas Turbine Engine by : Jhongwoo Peck
Download or read book Development of a Catalytic Combustion System for the MIT Micro Gas Turbine Engine written by Jhongwoo Peck and published by . This book was released on 2003 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Micro-scale Combustion Issues and Approaches by : Betty Bui
Download or read book Micro-scale Combustion Issues and Approaches written by Betty Bui and published by . This book was released on 2013 with total page 132 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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 Synopsis Combustion and Direct Energy Conversion in a Micro-combustor by : Yafeng Lei
Download or read book Combustion and Direct Energy Conversion in a Micro-combustor written by Yafeng Lei and published by . This book was released on 2006 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The push toward the miniaturization of electromechanical devices and the resulting need for micro-power generation (milliwatts to watts) with low-weight, long-life devices has led to the recent development of the field of micro-scale combustion. Since batteries have low specific energy (~200 kJ/kg) and liquid hydrocarbon fuels have a very high specific energy (~50000 kJ/kg), a miniaturized power-generating device, even with a relatively inefficient conversion of hydrocarbon fuels to power, would result in increased lifetime and/or reduced weight of an electronic or mechanical system that currently requires batteries for power. Energy conversion from chemical energy to electrical energy without any moving parts can be achieved by a thermophotovoltaic (TPV) system. The TPV system requires a radiation source which is provided by a micro-combustor. Because of the high surface area to volume ratio for micro-combustor, there is high heat loss (proportional to area) compared to heat generation (proportional to volume). Thus the quenching and flammability problems are more critical in a micro-scale combustor. Hence innovative schemes are required to improve the performance of micro-combustion. In the current study, a micro-scale counter flow combustor with heat recirculation is adapted to improve the flame stability in combustion modeled for possible application to a TPV system. The micro-combustor consists of two annular tubes with an inner tube of diameter 3mm and 30mm long and an outer tube of 4.2mm diameter and 30mm long. The inner tube is supplied with a cold premixed combustible mixture, ignited and burnt. The hot produced gases are then allowed to flow through outer tube which supplies heat to inner tube via convection and conduction. The hot outer tube radiates heat to the TPV system. Methane is selected as the fuel. The model parameters include the following: diameter d, inlet velocity u, equivalence ratio ø and heat recirculation efficiency n between the hot outer flow and cold inner flow. The predicted performance results are asfollowings: the lean flammability limit increased from 7.69% to 7.86% and the quenching diameter decreased from 1.3 mm to 0.9 mm when heat recirculation was employed. The overall energy conversion efficiency of current configuration is about 2.56.

Greatly expanded end-of-chapter problem sets and new areas of combustion engineering applications make it even easier for students to grasp the significance of combustion to a wide range of engineering practice, from transportation to energy generation to environmental impacts. Combustion engineering is the study of rapid energy and mass transfer usually through the common physical phenomena of flame oxidation. It covers the physics and chemistry of this process and the engineering applications—including power generation in internal combustion automobile engines and gas turbine engines. Renewed concerns about energy efficiency and fuel costs, along with continued concerns over toxic and particulate emissions, make this a crucial area of engineering. - New chapter on new combustion concepts and technologies, including discussion on nanotechnology as related to combustion, as well as microgravity combustion, microcombustion, and catalytic combustion—all interrelated and discussed by considering scaling issues (e.g., length and time scales) - New information on sensitivity analysis of reaction mechanisms and generation and application of reduced mechanisms - Expanded coverage of turbulent reactive flows to better illustrate real-world applications - Important new sections on stabilization of diffusion flames—for the first time, the concept of triple flames will be introduced and discussed in the context of diffusion flame stabilization
Book Synopsis Combustion in Piston Engines by : A. K. Oppenheim
Download or read book Combustion in Piston Engines written by A. K. Oppenheim and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 166 pages. Available in PDF, EPUB and Kindle. Book excerpt: Combustion in Piston Engines presents the technique of pressure diagnostics to measure the fuel consumption in an engine cylinder and to monitor the operation of micro-electronic systems for its control. It provides a recipe for bridging the gap between the hydrocarbon-fed combustion technology of automotive powerplants of today and electro-magnetic technologies of the future. The author proposes and introduces a model for the design of a MECC (micro-electronically controlled combustion) systems to modulate combustion in engine cylinders. This system yields significant reduction in the formation of pollutants and the consumption of fuel, so that, eventually, emissions using any clean hydrocarbon fuel will be acceptable and gas mileage could be doubled.
