概要:

application/pdf<br />Journal Article<br />Micro gas turbine systems have been developed as a portable power supply and the utilization of kerosene spray with pre-vaporized system was investigated for the combustor of the gas turbine. However there were few investigations about the spray characteristics with pre-vaporization. In this study, the characteristics of the kerosene spray with fuel vaporization on a hot wall were investigated experimentally. Twin … fluid atomizer was used for the spray formation. Heating block, which has a straight hole, was set at the nozzle exit of the atomizer. The wall temperature of the hole was changed from 292K to 433K. Effect of the wall temperature on mean diameter of spray droplets was investigated. Spray structure was visualized by the YAG laser system. As a result, mean diameter decreased when the wall temperature was around 360K. This temperature was close to a maximum vaporization temperature of the fuel. 続きを見る
