Abstract
A series of the experiments is planning to achieve a better mixing in an incomplete baffled and tall vessel with a modified impeller, which is an object of the industrial engineers. This work is the first one and is planned to establish the method of the measurement of the micromixing through examinations of well known combinations of a complete baffled vessel with the disc turbine(DT), marine propeller(PM). An incomplete baffled vessel with the inclined fan turbine(IFT) was also examined. A method of the continuous injection of the NaOH solution into the fluorescent dye solution is presented. Degree of the dispersion of the solute into the molecular level in the impeller region is very delayed and approximately depends on the power consumption per unit volume. Homogenization with the PM is performed at lower power input compared with that with the DT. The IFT is not preferable to apply for the tall vessel. However, it is found that a small baffle near liquid surface could promote the local micromixing near it.
