PARTICLE DISTRIBUTIONS IN STIRRED SOLID-LIQUID SYSTEMS. EXPERIMENTAL INVESTIGATIONS IN THREE DIFFERENT SCALES

摘要

Experimental results of local dispersed phase volume fractions in stirred vessels are presented. By means of an endoscope technique geometrically similar vessels with the diameters of 0.2,0.4 and 0.9 m were investigated at up to 70 different local positions. The results presented in this paper provide deeper insight into the complex fluid dynamics of stirred solid-liquid systems.
