Abstract

In order to enhance flame mixing, an annular combustor model with circumferential flow via oblique injection is developed in this paper, and the ignition process in the model is investigated experimentally. A high speed camera is used to record the flame crossover sequence, and the characteristics of flame propagating is compared with traditional normal injection way under different ignition modes, then the effect of equivalence ratio, flow rate and power to the light-round time is analyzed. It is found that the circumferential velocity component formed by oblique injection plays a key role in determining flame propagating process; when flow rate reaches a certain level, the flow acceleration coefficient influencing light-round time is mainly determined by the flow rate. © 2018, Science Press.
