Dispersion of a solids stream falling vertically into horizontal channel flow

摘要

The state of the liquid flow field is important in determining the extent of particle dispersion. For example, some electric are furnaces used in steelmaking inject pelletised direct-reduced iron feed into a quiescent steel system. This can result in the formation of `ferrobersgs' at the upper surface of the liquid [15]. Previously the authors [14] computationally investigated particle dispersion in a stagnant liquid with no heat transfer and identified limitations to particle mixing in such systems. Dispersion of particles is expected to be enhanced by motion of the liquid.
