【 摘 要 】

References(11)The power numbers of several kinds of impellers in rectangular eccentric vessels were correlated with Kamei et al.’s modified equation for a wide range of Reynolds numbers. The mixing patterns of these impellers were observed by using a decolorization method based on the reaction between sodium thiosulfate and iodine. A relationship was established between the power number diagram (NP–Re diagram) and the shape of the isolated zone. At low Reynolds numbers, isolated zones like donut rings were observed in the rectangular vessels and in a cylindrical vessel without baffles.
