... reactivity, which threaten the reactor safety. To accurately predict the void fraction for evaluation of accident consequence, drift flux model applied to gas-liquid metal two-phase flow is useful and need to be developed. In this contribution, an algebraic model aimed at bubble induced turbulence (BIT...

... velocity until now. So this study established the theory model for two-group interfacial area concentration weighted area-averaged gas velocity based on the drift-flux model for the two-phase dispersed bubble flow. The experimental data were selected from the published literature, which include...

... temperature was 220°C. Pb-Bi flow rates were measured and analytically estimated using balance condition between buoyancy force and pressure losses. The drift-flux model was used to determine the void fraction with assumption that bubbles sizes were dependent on the fluid surface tension and the density ratio...
