The modelling of natural gas combustion with detailed as well as reduced kinetic mechanisms has been subject to many publications already. Most of the mechanisms are validated at higher temperatures and ambient pressures. Only recently - in parallel to a g ...
This paper investigates different design strategies and process layouts for upgrading crude synthetic natural gas (SNG) produced from lignocellulosic biomass to grid quality. The design problem is outlined by studying the involved key aspects with respect ...
structural defects induced by He implantation in GaN epilayer at high fluence (1 X 10(17) He/cm(2)) and elevated temperature (750 degrees C) have been studied by conventional and high resolution transmission electron microscopy. In addition to the planar i ...
Cascade stilling basins system, consisting of a series of falls and stilling basins, may be a good alternative energy dissipation system for high head dams. Traditional design of such a system is based on a trial and error procedure by which the number and ...
The operation of the small size cogeneration gas engine (6 cylinders, 122mm bore, 142mm stroke) modified for unscavenged prechamber ignition was experimentally investigated. The objective was to evaluate the potential to reduce the exhaust gas emissions, p ...
Irradiation-induced disordering of bulk Ni3Al under 6 MeV Ni2+ irradiation is studied at room temperature. A self-consistent long-range-order quantification method for ion-irradiated intermetallics is presented using cross-sectional sample preparation and ...
The operation of a cogeneration internal combustion engine with unscavenged prechamber ignition was investigated. The objective was to evaluate the potential to reduce the exhaust gas emissions, particularly the CO emissions, below the Swiss limits (NOx an ...
In a first paper (part I), prechamber ignition in cogeneration natural gas engines has been shown to significantly intensify and accelerate the combustion process, offering a further potential to reduce the exhaust gas emissions while keeping efficiency at ...
The operation of a cogeneration internal combustion engine with unscavenged prechamber ignition was investigated. The objective was to evaluate the potential to reduce the exhaust gas emissions, particularly the CO emissions, without exhaust gas after trea ...
In order to determine the origin of the CO emissions from a cogeneration spark ignition engine fuelled with a lean natural gas-air mixture, the influence of several combustion chamber parameters have been measured in detail. In an attempt to interpret the ...
