Abstract

With the establishment of the appropriate porous media model of the combustor, temperature contour map on combustor cross section were simulated under the condition of different flow rate and different porosity in the Fluent software, and experimented to verify the simulation. The results show that: Flame core position moves toward the export with the increase of flow rate, but when the flow increases to a certain amount, the outlet temperature rises significantly. temperature distribution is the best when flow rate is 120 mL/min; With the decrease of the porosity, the flame core position moves to the entrance. Wall average temperature of the combustor is the highest when porosity is 0.4.
