Abstract:

This report presents models for the hot turbulent plumes above tactical battlefield fires. Models are developed for the plume radius, temperature, and rise velocity as a function of altitude given the initial fire conditions. The strength of the hot air turbulence is related to the plume parameters for several assumed flow conditions. The turbulent propagation effects are evaluated for optical beams whose paths intersect the plume. Sample results are presented for coherence length, short- and long-term beam spreading, and beam jitter. Author
