“…5 The plunging jet can be used for the mixing of different liquids, which can be achieved by using other mixer processes such as the jet mixer and the mechanical or static mixer. 6 The jet mixer has several advantages over the mechanical mixer because it has a low sealing problem, 7 low energy consumption, 1 cheaper installation, 8 and a lower mixing time. 9 For the mixing of the liquid−liquid phase, the jet system has a higher liquid mixing and mass-transfer operation.…”

The present work focuses on studying the degree of liquid–liquid axial dispersion in a jet-driven mixing column. The online conductivity measurement was performed to study the residence time distribution. The effects of the jet velocity and dispersed phase volume on mixing characteristics were studied. The axial dispersion coefficient range was found to be 25.6 to 106 cm2/s. A general correlation is developed to predict the axial dispersion coefficient based on various operating variables. A mechanistic model is proposed to interpret dispersion due to the turbulence and phase circulation inside the jet-driven mixing column. Based on the velocity distribution model, the velocity characteristic factor and the dispersion factor of drop motion were also enunciated. The present study may be helpful for further understanding a two-phase system in industrial applications, especially in liquid–liquid extraction.

“…M ixed flow agitators borrow characteristics fro m both radial flo w and axial flow agitators. As liquid flows through the impeller of a mixed flow agitator, the impeller blades push the liquid out away fro m the agitator shaft and to the agitator suction at an angle greater than 90 o [8]. A centrifugal agitator with a single impeller that can develop a differential pressure of more than 150 psi between the suction and the discharge is difficu lt and costly to design and construct.…”

This research is to design and implement a new kind of agitators called d ifferential agitator. The DifferentialAgitator is an electro-mechanic set consists of two shafts. The first shaft is the bearing axis wh ile the second shaft is the axis of the quartet upper bearing impellers group and the triple lo wer group wh ich are called as agitating group. The agitating group is located inside a cy lindrical container equipped especially to contain square directors for the liqu id entrance and square directors called fixing group for the liquid exit. The fixing group is installed containing the agitating group inside any tank whether fro m upper or lower position. The agitating process occurs through the agitating group bearing causing a lower pressure over the upper group leading to withdrawing the liquid fro m the square directors of the liquid entering and consequently the liquid moves to the denser place under the quartet upper group. Then, the liquid moves to the so high pressure area under the agitating group causing the liquid to exit fro m the square directors in the bottom of the container. For improving efficiency, parametric study and shape optimization has been carried out. A numerical analysis, manufacturing and laboratory experiments were conducted to design and imple ment the differential agitator. Knowing the material prosperities and the loading conditions, the FEM using ANSYS11 was used to get the optimu m design of the geometrical parameters of the differential agitator elements while the experimental test was performed to validate the advantages of the differential agitators to give a h igh agitation performance of lime in the water as an example. In addit ion, the experimental work has been done to e xpress the internal container shape in the agitation efficiency. The study ended up with conclusions to maximize ag itator perfo rmance and optimize the geometrical parameters to be used for manufacturing the differential agitator.
