DYNAMICAL BEHAVIOR OF A PREMIXED TURBULENT OPEN V-FLAME

The level-set approach of Osher & Sethian to tracking interfaces is su ccessfully adapted to the simulation of a premixed turbulent open V-fl ame including the effects of exothermicity and baroclinicity. In accor d with experimental observations this algorithm, along with a flame an choring scheme, predicts flame cusping for a case in which a strong vo rtex pair interacts with the flame front. The computed velocity and sc alar statistics obtained for the turbulent V-flame compare reasonably well with experimental results by Cheng & Shepherd, and demonstrate th e importance of flame-generated vorticity in the determination of flam e dynamics and product velocity characteristics.
