Study of diffusion jet flame characteristic under centrifugal force

The paper adopted the straight and curving passages to investigate the flame characteristic under the same test conditions. The diffusion jet flame characteristic was studied under high centrifugal force. Through comparison and analysis of the test results, it was obviously observed that the flame speed was faster in the curving passages under buoyant force action resulting from a high centrifugal force. The high centrifugal force made the diffusion flame speed faster and weakened the interference of crossflow. The diffusion flame could mix and react with the mainstream much more easily. The penetration depth of jet flame in the crossflow was increased.
