This book was released on 2009 with total page 13 pages. Available in PDF, EPUB and Kindle. Book excerpt: Under this award the fluid mechanics measurement capabilities of the combustion and fuels laboratory of the University of Southern California were upgraded notably. Thus, the needs for determining flame properties of fundamental and practical importance can be met readily. The experimental data so obtained will be used for the validation of chemical kinetic and diffusion models for hydrocarbon fuels used in air-breathing devices that are of interest to the Air Force; furthermore, the data contain important information related to the performance of various practical fuels and will be useful in defining the operational range of advanced propulsion systems, such as scramjets. The acquired instrumentation involves high-resolution, high accuracy laser-based systems and subsystems and constitutes a major improvement of current capabilities in the principal investigator's (PI's) laboratory. This improvement enhances the quality of ongoing research that is conducted under AFOSR support significantly. Three state-of- the-art velocity measurement systems were developed to complement an existing digital particle image velocimetry (DPIV) system that was acquired previously under AFOSR support. The first velocity measurement system is a compact laser Doppler velocimeter (LDV). The other two are DPIV systems, which were developed around a high-power YAG laser that is available to the PI at no cost to AFOSR. After determining the velocity fields in flames, fundamental flame properties can be derived, such as laminar flame speeds, as well as ignition and extinction limits. The sensitivity of those properties to both chemical kinetics and molecular transport can be large, so that validation and/or optimization of various models can be achieved. The parameter space of the PI's ongoing research is extensive, as it involves a large number of fuels, such as neat hydrocarbons, jet fuels and their surrogates, fuel-air ratios, initial reactant temperatures, and thermodynamic pressures.
Book Synopsis Development of a Laminar Flame Test Facility for Bio-diesel Characterization by :
Download or read book Development of a Laminar Flame Test Facility for Bio-diesel Characterization written by and published by . This book was released on 2009 with total page 71 pages. Available in PDF, EPUB and Kindle. Book excerpt: The thesis examines the current testing standards for diesel fuels and establishes the relevance of such testing standards to bio-derived diesel fuels. There is a need for more detailed kinetics information for bio-diesel fuels to allow exploration of issues in engine and fuel design. Flame studies can provide overall chemical kinetic information that is currently lacking in the literature for bio-diesels fuels. An experimental apparatus to measure laminar flame speeds was designed and implemented to convey overall chemical reaction rate information. This work addresses three major aspects of such design: combustion chamber, auxilliary systems (gases and fuel supply, ignition and control), and measurement systems. Test rig characterization was attempted; however, critical ignition and fueling issues were uncovered during experimentation. Suggestions for future work provide solutions and improvement pathways to the current design.

Download or read book NASA Grc's High Pressure Burner Rig Facility and Materials Test Capabilities written by National Aeronautics and Space Administration (NASA) and published by Createspace Independent Publishing Platform. This book was released on 2018-06-15 with total page 34 pages. Available in PDF, EPUB and Kindle. Book excerpt: The High Pressure Burner Rig (HPBR) at NASA Glenn Research Center is a high-velocity. pressurized combustion test rig used for high-temperature environmental durability studies of advanced materials and components. The facility burns jet fuel and air in controlled ratios, simulating combustion gas chemistries and temperatures that are realistic to those in gas turbine engines. In addition, the test section is capable of simulating the pressures and gas velocities representative of today's aircraft. The HPBR provides a relatively inexpensive. yet sophisticated means for researchers to study the high-temperature oxidation of advanced materials. The facility has the unique capability of operating under both fuel-lean and fuel-rich gas mixtures. using a fume incinerator to eliminate any harmful byproduct emissions (CO, H2S) of rich-burn operation. Test samples are easily accessible for ongoing inspection and documentation of weight change, thickness, cracking, and other metrics. Temperature measurement is available in the form of both thermocouples and optical pyrometery. and the facility is equipped with quartz windows for observation and video taping. Operating conditions include: (1) 1.0 kg/sec (2.0 lbm/sec) combustion and secondary cooling airflow capability: (2) Equivalence ratios of 0.5- 1.0 (lean) to 1.5-2.0 (rich), with typically 10% H2O vapor pressure: (3) Gas temperatures ranging 700-1650 C (1300-3000 F): (4) Test pressures ranging 4-12 atmospheres: (5) Gas flow velocities ranging 10-30 m/s (50-100) ft/sec.: and (6) Cyclic and steady-state exposure capabilities. The facility has historically been used to test coupon-size materials. including metals and ceramics. However complex-shaped components have also been tested including cylinders, airfoils, and film-cooled end walls. The facility has also been used to develop thin-film temperature measurement sensors.

This book was released on 2008-10-19 with total page 130 pages. Available in PDF, EPUB and Kindle. Book excerpt: The 21st Century Truck Partnership (21CTP), a cooperative research and development partnership formed by four federal agencies with 15 industrial partners, was launched in the year 2000 with high hopes that it would dramatically advance the technologies used in trucks and buses, yielding a cleaner, safer, more efficient generation of vehicles. Review of the 21st Century Truck Partnership critically examines and comments on the overall adequacy and balance of the 21CTP. The book reviews how well the program has accomplished its goals, evaluates progress in the program, and makes recommendations to improve the likelihood of the Partnership meeting its goals. Key recommendations of the book include that the 21CTP should be continued, but the future program should be revised and better balanced. A clearer goal setting strategy should be developed, and the goals should be clearly stated in measurable engineering terms and reviewed periodically so as to be based on the available funds.
