Experimental investigations on the effects of water vapor and oxygen concentrations in the ambience on the burning constant, lifetime and residuals of single isolated xylene, isobutanol and ethanol droplets

During spray combustion, the complex oxidizing atmosphere makes the direct experimental investigation of droplet evaporation and combustion challenging. Within this study, the effects of water vapor as well as the concentrations of oxygen and nitrogen in the atmosphere on the single isolated droplet combustion were experimentally investigated using a high-speed digital camera. An in-house made piezoelectric droplet-on-demand generator was...
