Abstract
The optical effects of a hot fire Plume can only be calculated in a real-time situation if the dynamics and thermodynamic properties of the plume can be calculated in real-time. A method is presented which can be anplied to the above Problem and many other physical problems. The procedure is to break the Physical nrocess into a sequence of processes to be performed in a cyclic manner, one complete cycle ner time step, with each cycle ending on a physically acceptable state. Calculations are shown first for a steady radially symmetric Plume over a uniform source. Calculations are nresented which show agreement with the much slower conventional approach. The method is then extended by relaxing the assumntion of instant mixing. Radially varying sources, chemical constituents from the flame and atmospheric humidity, are also included.
