Research on the Fuel Capture on the Surface of V-Gutter Flameholder

The fuel capture rale on the surface of v-gutter flamcholdcr has been investigated in this paper both experimentally and theoretically. By means of v-shaped capture gutters, a new method for measuring the fuel capture on the surface of flameholder has been proposed. The relationship between fuel capture rate and individual parametes has been set up and analysed. Based on this relationship, an empirical expression has been obtained. In the calculation, the concept considering the edge of fuel droplet groups as reference trajectory has been proposed and the most of the factors which influence the fuel capture were considered. The fuel capture rate on the surface of v-guttcr flameholder has been calculated and the results of experiments are in good agreement with the calculations.
