Experimental Study on Atomization and Drop-Size Distribution of Liquid-Liquid Systems

摘要

In the paper the ice slurry production system is introduced and the phenomenon of drop formation is discussed. Drop formation in liquid-liquid atomization processes is one of the key technologies of liquid-liquid circulating fluid bed (CFB). A high resolution digital camera and image processing were employed to investigate the process of drop formation in a normal CFB experimental system. The photos and sizes of drops in the whole flux range were obtained from experiments, and the distribution function was applied to analyze the drop-size distributions (DSD). Experimental results indicate that DSD from a certain flux is in good agreement with Rosin-Rammler distribution function(RRDF).
