School of Mechanical Engineering, Purdue University Burke-Schumann Diffusion Flame Analysis Additional assumptions: 1. Velocities of fuel and oxidizer streams are equal 2. Zero radial velocity everywhere: implies that v x = constant = ref v x,ref everywhere 3. Buoyancy neglected 4. D = constant = ref D ref (actually proportional to T 1/2 ) 5.  11 vv xr r f r f rx rr   
