Flow Characteristics Downstream of V-Gutter Type Flame Holder in High Speed Flow,
Abstract
Detailed velocity data downstream of annular v-gutter type flame holders in high speed flows was obtained using a fiber LDV. In order to measure fluctuating velocity of the flow at high data rate, the fiber LDV system was optimized for use in high speed flow conditions. It was found that twin oscillating recirculating vortices were formed behind the v-gutter and that these vortices were released and flowed downstream. The peak frequencies and scale of vortices were observed by FFT processing of time series velocity data. The vortex scale profile was almost independent of bulk velocity. (Author)
