Abstract:The lance is a critical component of the bottom-blowing pool melting process,
and its placement has an important impact on the pool?s gas-liquid two-phase
flow. In this study, a mathematical model of the bottom-blowing process is
established, and the flow pattern, trajectory, wake vortex, and velocity of
bubbles under four lance spacings are simulated. Results show that there are
three basic bubble flow patterns appear in the flow field: bubbles coalesce
before leaving the nozzle (Pattern I),… Show more
