Measurements of Characteristics of Evaporating Sprays : Quantitative Analysis of Fuel Droplet Diameter
An experimental study was carried out to verify the feasibility of a quantitative analysis of fuel droplet diameter at high pressures and temperatures in combustion systems. A fueling system was developed to atomize fuel into droplets of the same diameter. Using this system, fueling was made into a...

| description | An experimental study was carried out to verify the feasibility of a quantitative analysis of fuel droplet diameter at high pressures and temperatures in combustion systems. A fueling system was developed to atomize fuel into droplets of the same diameter. Using this system, fueling was made into a visualized device where high pressure and temperature nitrogen flowed under steady-state conditions. The laser induced fluorescence method was utilized to determine n-dodecane fuel and iso-octanefuel droplet behavior and the phase Doppler particle analyzer was used to measure the diameter and velocity of the droplets. As a result, it was confirmed that a quantitative analysis of fuel droplets is possible. The results indicate that due to its lower boiling point, iso-octane droplets tend to evaporate much faster the n-dodecane droplets. |
