dc.description.abstractAn experimental work was carried out to investigate the effect of acoustical excitation on the combustion of a fuel jet in a cross-wind of air. Excitation was found to augment mixing. Increasing the exciting amplitude augments the performance up to the quenching limit, while increasing Strouhal number (frequency of excitation) reduces mixing time scale with an optimum of 0.25. Circular and elliptical nozzles were investigated, in addition to a cup design. Low momentum ratios (Fuel jet to cross flow) were found to enlarge the recirculation zone, with an extended stable range of Reynolds number for the cup under excitation. Reduction of carbon monoxide, unburned hydrocarbons, and flame length by excitation was confirmed for all nozzle geometries, while the cup exhibited the largest reduction, with a fairly comparable quality for the elliptical excited flame. It is concluded that the cup-nozzle plays a significant role in enhancing flame stability (flame not blowing off) and quality, due to the enriched recirculation zone, and the more complicated jet interaction to prevent quenching.en
