Comparison density of maximal energy for mixing process using the same agitator in rotational and reciprocating movements

The aim of this paper is to present experimental investigations of the influence of the new construction of agitator with the inclined blades on the maximal power consumption and mixing time. The comparison of two kinds movement (rotational or reciprocating) of the same agitator is based on the so-called density of maximal mixing energy. This energy is defined as the product of the power input to the mixed liquids and mixing time. The power consumption is calculated from the measured force acting on a dynamometric ring. A thermal-response technique is used for mixing time measurements. The analytical form of the mixing process characteristics are predicted in the present paper and the experimental database is generalised without the break through the all regions of flow in a relatively simple manner.
