Abstract

Inner and outer swirl produced by cyclone separator have the potential of stabilizing flame and cooling wall, therefore, in this paper, RSM model was used to simulate flow characteristics of a swirl-cooled combustion chamber. The results show that swirl-cooled combustion chamber can achieve inner and outer swirl flow, and has good cooling effect of the wall. Under cold and hot conditions, the total pressure loss coefficient is 0.9% and 1%, showing low resistance characteristics of the structure, the average boundary of inner and outer swirl is 70% of the swirl radius. The boundary of combustion increases with the increase of fuel injection rate. The combustion zone is biggest when fuel injection rate is 12 m/s, the average is 56% of the radius.

Key words： cyclone separator; numerical simulation; flow characteristics
