A reduced mechanism for ethylene/methane mixtures with excessive NO enrichment

Experimental Study of Direct Water Injection Effect on NOx Reduction from The Gas Fuel

“…Also note that all of these values considering that the best NOx reduction value at the three conditions W/F ratio 0.2, 0.3 and 0.4 is at injected water inclination angle 45° due to the explained reason before. The results are in agreement practically with Ayed et al, [16] and Luo et al, [17].…”

“…It provides the air to the combustion chamber for a fuel burning combustion. The discharge from the air compressor end is connected with the primary air pipe which is fitted into the fuel nozzle pipe by 45 degree angle and 10 cm before the nozzle tips, the connection is through a flexible hose and an air control valve (17) to adjust the inlet air for the combustion process and measured the air flowrate with a similar rotameter of the gas fuel as well [23]. For the water injection kit, the water is injected through a clean glucose lashes with a calibrated ruler from 1 to 500 mm/min (18) and hanged on an ironed stand with a height 130 cm from the injection point to be simulated as a head tank [21].…”

Analysis of Kinetic Reaction Mechanisms

“…The DRG method was first applied to a model system of ethylene combustion (Lu and Law 2005;Luo et al 2011) with a full scheme of 70 species. A value of ε of 0.16 gave a skeleton scheme of 33 species, i.e.…”

“…The DRGEP approach has been applied adaptively in order to produce on-the-fly reduced mechanisms for n-heptane (Shi et al 2010b) and gasoline surrogate mixtures (Liang et al 2009b;Shi et al 2010a) in simulations of homogeneous charge compression ignition. Other applications of the DRG method and its extensions to skeletal model reduction include modelling the high-temperature combustion of H 2 /CO/C 1 ÀC 4 hydrocarbons (Wang 2013), methane oxidation (Jiang and Qiu 2009), nitrogen oxide emissions and their control (Lv et al 2009;Luo et al 2011), the combustion of n-heptane (Liang et al 2009a;Wang et al 2013;Bahlouli et al 2014), surrogate jet fuels (Naik et al 2010), methyl decanoate (a large methyl ester used as a surrogate for biodiesel, (Seshadri et al 2009)), surrogate biofuels (Luo et al 2010a, b;Malik et al 2013) and the oxidation of iso-octane (Kelley et al 2011). The number of species required in the locally reduced models varies throughout the calculations but reaches a maximum of about one third of the number of initial species.…”

“…However, methane (CH 4 ) and ethylene (C 2 H 4 ) are short chain hydrocarbons that are major products resulting from thermally cracked kerosene. Additionally, fuel components with dramatically different chemical properties such as methane and ethylene can be used as surrogate mixtures for more complex fuels (Luo et al, 2011). As a result methane and ethylene are often used as surrogate fuels in both simulations and experimentation (Wu et al, 2017).…”
