Numerical Investigation on Three-dimensional Flame Acceleration Induced by an Obstacle and Tube Internal Walls

YANG Hong wei,FAN Bao chun,LI Hong zhi (Nanjing University of Science and Technology,Nanjing 210094,Jiangsu,China)  
Based on k ε turbulence model and an improved EBU Arrhenius combustion model,the theoretical model of flame acceleration by turbulence is established by modifying the source term in the equations.The additional influence of obstacle is considered.In this paper,SIMPLE algorithm is adopted to solve the governing equations.The wall function is chosen to deal with the boundary near the wall.The Phenomena that flame is accelerated by an obstacle and tube wall are investigated numerically.The results show that both obstacles and tube internal wall could accelerate the flame.The acceleration effect by an obstacle is more obvious.The mechanism of flame acceleration is explored in this paper too.
