A correlation for pool entrainment phenomenon

The present work aims to study the phenomena of droplet entrainment from water pool in a confined atmosphere, which could be either consequence boiling or depressurization. Eventually, these droplets are entrained by streaming gas (superficial velocity) settling down due gravity. number correlations developed so far quantify based on empirical, semi-empirical and theoretical approaches, but they have been generally limited specific flow-regime pool, thermal hydraulic conditions even geometry. In this context, develop an empirical correlation cover flow regimes bubbly churn turbulent, applied wide range geometries. shows increase until maximum about 2.10-4, corresponding superficial velocity 0.05 m/s for regime, then slight decrease 2·10−5, transition regime 0.1 m/s, sharp turbulent as goes up 5 m/s. experimental database used covers broader boundary conditions, namely pressure [1 bar–15 bar], condition [subcooled – boiling], vessel diameter [0.19 m- 3.2 m], [0.1 m–1.4 5.0 Therefore, proposed constitute important tool transfer results reactor application.
