Time to Equilibrium and Transient Drop Size in Turbulent Flow

4 Time to Equilibrium and Transient Drop Size in Turbulent Flow 

Several investigators, including Chen and Middleman (1967), Arai et al. (1977), and Wang and Calabrese (1986), have reported that after introduction into the tank, several hours are required for a dilute dispersion to reach the equilibrium 

Using an intuitive approach, several researchers have proposed that the time for ds2 to reach equilibrium could be described by analogy to reaction kinetics  

The aforementioned investigators found that after a relatively short time, the DSD became normally distributed in volume, like the equilibrium DSD discussed in Section 12-2.3.2. Both Narsimhan et al. (1980) and Chang (1990) found that the data from many experiments could be collapsed to a single curve
