抄録

The effect of baffles on the mixing of bath liquid and solid particles was investigated using a water model for the mechanically stirred vessel. The baffle whose width is 1/10 of the vessel diameter was enough to enhance the liquid-particles mixing. The LDV measurement showed the formation of the unsteady vertical flow by the baffle. The concept of information entropy was introduced for the evaluation of the mixing properties of the reactor. The vessel was divided into 35 regions and the transition probability for each region was estimated from the velocity profiles obtained from the LDV measurement. The complete mixing time was predicted by the calculation and compared with the observations.
