Abstract: The use of biogas has currently two disadvantages. First, processing biogas to natural gas quality for feeding into the natural gas grid is a rather energy-consuming process. Second, the conversion into electricity directly ...

Abstract: Detailed information of the thermodynamic parameters, system performance, and operating behavior of aircraft auxiliary power units (APU) cycles is rarely available in literature. In order to set up numeric models and study ...

Abstract: As an alternative to the commonly used swirl burners in microgas turbines (MGT), the FLOX®-based combustion concept promises great potential for the nitric oxide emission reduction and increased fuel flexibility. Despite ...

Abstract: The effect of superheated liquid fuel injection on the performance and emissions of a single nozzle combustor was investigated. Combustion of the lean premixed flames was achieved using a combination of jet and swirl as a ...

Abstract: A newly developed gas turbine combustor system based on the swirl-assisted jet-stabilized concept using Jet A-1 and natural gas as reference fuel is tested under wet conditions to evaluate its combustion characteristics ...

Abstract: A major challenge for gas turbine combustor technology is the emission of NOx and carbon monoxide (CO). Achieving an optimal premixed, prevaporized, dry low-NOx condition is a critical issue for liquid fuel combustors. To ...

Abstract: Auxiliary power unit (APU) operators face increasingly stricter airport requirements concerning exhaust gas and noise emission levels. To simultaneously reduce exhaust gas and noise emissions and to satisfy the increasing ...

Abstract: Recognizing the attention currently devoted to the environmental impact of aviation, this three-part publication series introduces two new aircraft propulsion concepts for the timeframe beyond 2030. The first part focuses ...
