Aggregates motion in an agitated three-phase slurry reactor

Mostrar todas las versiones(2)

The motion of a large particle representing an aggregate in a three-phase slurry reactor was followed by the Radioactive Particle Tracking technique to analyze the effect of the agitating velocity and of the presence of suspended solids. Gas-liquid system employed was octane-nitrogen and the suspend...
