The combustion characteristics of a swirling inverse diffusion flame (IDF) upon variation of the oxygen content in the oxidizer were experimentally studied. The oxidizer jet was a mixture mainly composed of oxygen and nitrogen gases, with a volumetric oxygen fraction of 20%, 21% and 26%, and...

An experimental study was performed to investigate the effects of the nozzle length on the air-pollutant-emission and noise-radiation behaviors of a burner utilizing a multi-fuel-jet inverse diffusion flame (MIDF). Comparison of the experimental results obtained from two MIDF burners, one with a...

The overall pollutants emission from impinging swirling and non-swirling inverse diffusion flames (IDFs) was evaluated quantitatively by the [`]hood' method. The results of in-flame volumetric concentrations of CO and NOx and overall pollutants emission of CO and NOx in terms of emission index...

This paper reports an experimental investigation of the pollutant emission and noise radiation characteristics of both open and impinging inverse diffusion flames (IDFs), produced by five burners of different air port diameter (dair=5, 6 and 6.84mm) and air-to-fuel spacing (S=8, 11.5 and 15mm)....

This study investigated the influence on the combustion characteristics and particulate emissions of a diesel engine fueled with DBE (diesel-biodiesel-ethanol) blended fuels. The effects on in-cylinder pressure, heat release rate, combustion duration, diffusion fuel mass, BSPM (brake specific...

This paper is an experimental study on the heat transfer optimization of an Innovative Inverse Diffusion Flame (IDF) characterized by a central air jet surrounded by an array of fuel jets for impingement heating. It is found that the diameter ratio between air port and fuel port (da/df) exerts...

This paper is an experimental study on the combustion optimization of an Innovative Inverse Diffusion Flame (IDF) characterized by a central air jet surrounded by an array of fuel jets for impingement heating. An extensive investigation has been performed to explore the effects of the diameter...

An experimental investigation was conducted on the combustion, performance, regulated and unregulated emissions of a diesel engine with naturally aspirated hydrogen at the engine speed of 1800revmin−1 under five engine loads. Hydrogen was added to provide 10%, 20%, 30% and 40% of the total...

In this study, experiments were conducted to examine the effect of using a mixture of diesel and n-pentanol, which is one of the second-generation biofuels with comparable properties to diesel fuel, as fuel on the combustion, performance, and gaseous and particulate emissions of a...
