Prediction of release rate of burnt sodium as aerosol

Evaluation of the consequences of sodium poor fire requires a prediction mo del that can calculate the fractions of the aerosols of Na2O and Na2O2 bein g transported into the atmosphere and onto the sodium pool surface from the reaction zone. In the present model, we applied the laminar diffusion flam e theory in a thin layer in the neighborhood. of the pool surface. The comb ustion was modeled assuming the instantaneous chemical equilibrium because the chemistry is fast compared with the mixing. The aerosol transport was a ssumed to be due to a sum of the drag force, the thermal force and the grav ity. The calculated results are in good agreement with experimental data ob tained by other investigators for the burning rates and the aerosol release fractions of sodium pool fire. This analysis forms the basis of prediction of aerosol release fraction in the sodium pool fire.
