초록정보

This study has been performed; 1) to show the effect of various parameters (swirl number, equivalence ratio, and burner geometry) on the shape of the swirling flame 2) to examine closely the characteristics of the flow fields of strongly swirling flames and turbulent swirling jets. The experiment was made by using dual beam LDV system for velocity measurement, and by using Type-R thermocouple(Pt-Pt/Rh 13\%) for temperature measurement. Two type of stable flames with strong swirl, Type I and Type V, were choosen to investigate the flow field. For the flame of Type I, the central jet penetrates the recirculation zone which is reduced to subsidiary reaction zone, and the luminous flame zone is constituted downstream. On the other hand, for the flame of Type V the fuel jet cannot penetrate central recirculation zone, but is shoved out in radial direction so that all most boundary of the recirculation zone becomes the flame front. In this case the recirculation zone is more expanded than that of cold jet, as the burned gases which constitute the recirculation zone are of low density due to their high temperature.
