To analyze the effect of bottom diameter of cone, diameter of oil inlet and equivalence ratio, n swirl-cooled combustor chamber, Reynolds stress model (RSM) was used for simulation of combusting characteristics of the chamber. The results show that: swirl-cooled combustor chamber could utilize the structure of inner and outer swirl to achieve wall-cooled effect. High ratio of bottom diameter of cone to the diameter of oil inlet results in failure of wall-cooled effect, but the smaller proportion may generate worse wall-cooled effect. Reasonable matching relation of bottom diameter of cone and the diameter of oil inlet could realize a wide operating range. The optimum matching in this paper is 15 mm for the bottom diameter of cone and 5 mm for the diameter of oil inlet.
