선회익위치(旋回翼位置)에 따른 선회화염(旋回火焰)에 관한 연구(硏究)

A Study on the Swirl Flame according to the Swirler Position

The swirl flame was investigated experimentally by measuring the temperature distribution, and the combustion gas concentrations. The flame structure of the swirl flame was influenced not by the swirl vane angle but by the swirler position. Due to the momentum loss as the swirler position was moved downward under the nozzle exit, the flame length was increased. Meanwhile the temperature and $CO_2$-concentrations were decreased.
