The Burke-Schumann spray diffusion flame in a nonuniform flow field

The uniform, constant velocity profile assumption of the classical Burke-Schumann diffusion flame model is relaxed to permit more realistic duct entrance velocity profiles to be accounted for. An approximate model is formulated to include the supply of a spray of liquid fuel in the inner duct of the coflow configuration. For appropriate operating conditions (the characteristic flow time less than the characteristic vaporization time) it is shown...
