...-carbon bonds, considerably reduces the formation of soot particles. To meet the challenges of a more flexible and sustainable power generation, a detailed understanding of its combustion properties is essential for its safe and efficient utilization, neat or in blends. In this work, two fundamental...

...Alessio Suman; Alessandro Vulpio; Michele Pinelli; Lorenzo D'Amico The detrimental effects generated by the gas turbine fouling phenomenon are well known. Due to soil and soot particles ingestion, gas turbines experience performance drops related to greater fuel consumption and even lower...

... process. The results indicate that turbulence term enhances the rate of breakup, resulting in more new droplets and smaller droplet sizes, leading to high evaporation rate with more evaporated mass. The model is also applied to simulate combustion and soot formation process of diesel. The effects...

... in modern diesel engines. The pilot injection conditions definitely affect the flame development and soot formation in the main spray combustion, and consequently enhance or weaken the smoke reduction ability of post injection. Thus it is necessary to examine the smoke reduction effect corresponding...

..., 2013; published online October 28, 2013. Editor: David Wisler. 11 08 2013 14 08 2013 Swirl-stabilized, nonpremixed ethylene/air flames were investigated at pressures up to 5 bar to study the effect of different operating parameters on soot formation and oxidation. Focus...

... exchangers. EGR particulate fouling soot hydrocarbons heat exchanger Heavy-duty transportation relies on diesel engines, which provide higher torque output and increased fuel economy compared to conventional gasoline engines. Even with these merits, the tail-pipe emissions, mainly oxides...

...Klaus Peter Geigle; Jochen Zerbs; Markus Köhler; Michael Stöhr; Wolfgang Meier Sooting ethylene/air flames were investigated experimentally in a dual swirl gas turbine model combustor with good optical access at atmospheric pressure. The goals of the investigations were a detailed characterization...

... estimation of soot loading, which is instrumental to ensuring optimal performance of the whole engine-after-treatment assembly, is still a major challenge. In fact, several highly coupled physical-chemical phenomena occur at the same time, and a vast number of engine and exhaust dependent parameters make...

...William F. Northrop; Stanislav V. Bohac; Jo-Yu Chin; Dennis N. Assanis Partially premixed low temperature combustion (LTC) is an established advanced engine strategy that enables the simultaneous reduction of soot and NO x emissions in diesel engines. Measuring extremely low levels of soot...

...Arindam Samanta; Ranjan Ganguly; Amitava Datta In the present work, a numerical analysis has been presented to show the variations in flame structure, flame radiation, and formations of soot and NO in methane-air laminar nonpremixed flames with different CO 2 dilutions of fuel. It is observed...
