SPRAY FORMATION BY FLASHING OF A BINARY MIXTURE: AN ENERGY BALANCE APPROACH
RESUMO
An attempt is made to correlate droplets' Sauter mean diameter with the thermodynamic properties of a binary mixture at initial conditions, by means of the process efficiency interpretation and the "available energy" theorem. Two limiting cases are considered; an isothermal process and an adiabatic process. An idealized form of the isothermal model results in a simple correlation that clearly explains some of the relationships between the initial conditions of the binary solution and the spray quality.
The results of the adiabatic model seem to be more realistic and fit the experimental observations better. The process efficiency is found to be about 2 × 10−4. It is possible that the process efficiency depends to a limited extent on the initial conditions.
