Spatially nonuniform distributions of droplet concentration and velocity can lead to asymmetrically distorted spray diffusion flames. A mathematical model is developed and its equations are solved to try to analyze the sort of three-dimensional asymmetries that can arise. Calculated data indicate the extent to which spray-related parameters (fuel volatility, droplet size, nonuniform patternation) can affect flame shape and height, and the fuel waste due to droplets surviving the combustion region.
