The paper establishes physical and mathematical model to study the laminar diffusion combustion, which is formed by concentric jet characteristics of DME/air. It uses commercial simulation software fluent to simulation laminar diffusion combustion process to get the temperature field distribution in different conditions and analyze the simulation results. Simulation results indicates that the faster fuel flow velocity, the higher combustion temperature and higher efficiency without rotate speed conditions, But with the rotate speed, the combustion temperature and the combustion efficiency decrease to half of their original. However, increasing fuel flow velocity on the basis kind of circumstance can make the combustion temperature and efficiency increased.
