A new mathematical analysis of the dynamics of laminar spray diffusion flames in the vicinity of a vortex flow fieldis presented. The governing equations for a spray evaporating in an unsteady vortex are studied. New similarity solutions are found for the dynamics of the spray and the flame it supports. Analytical solutions for the spray flames are derived using Schvab-Zeldovich parameters, through which the radial evolution of the flames is found. The results based on the solution reveal the significant influence the droplets size has on the diffusion flame dynamicsin the vicinity of vortical flows.
