Abstract

The Sanmeler, an impeller with asymmetric geometry developed by a Japanese company, can be used over a wide range Reynolds number from laminar to turbulent flow regions. Visualization of streak lines showed that their pattern spread quickly throughout the mixing vessel regardless of the liquid height, indicating that the Sanmeler had good mixing performance. The power consumption of the Sanmeler was correlated with simple modification of the correlations of other wide-paddle impellers.

A method was developed to quickly evaluate the streak line pattern in a laminar mixing vessel by numerical analysis. The primary flow in a laminar mixing vessel is the rotational flow, but the secondary flow as the upper and lower circulation flow determines the quality of the mixing. The three-dimensional steady velocity component of r–θ–z was regarded as the two-dimensional non-steady velocity component of r–z–t. As a result, the calculated streak line pattern agreed qualitatively well with the experimental pattern, and calculating time was reduced substantially. By using the present method to translate the three-dimensional steady flow to a two-dimensional unsteady flow, streak line patterns were easily visualized from video data with PIV at low Reynolds number. It was found that the mixing performance of impellers, including some wide-paddle impellers developed by a Japanese company, could be estimated quickly by this method.

New anchor impellers were developed for mixing non-Newtonian fluids such as plastic fluid and viscoelastic fluid. This new mixing system combining an unsteady rotating vessel with a new anchor impeller could easily mix a non-Newtonian fluid. A unique flow pattern was found on mixing viscoelastic fluid using an eccentric plate type shaft, and this plate-type shaft was applied to the new anchor impeller.

Streak line patterns of several wide-paddle impellers developed by mixer companies in Japan were observed from laminar to turbulent flow regions. The power consumption of all wide-paddle impellers examined was correlated by using the same correlations as in our previous work, but the mixing mechanism of these impellers in the laminar flow region changed greatly with the kind of impeller. It was found that these wide-paddle impellers had distinctive patterns of streak lines depending on the operation conditions. In particular, liquid height greatly affected the streak line pattern. Furthermore, it was found that the impeller Reynolds number was a parameter that controlled the streak line pattern.

The elementary mechanism of laminar mixing is analyzed with numerical simulation from the point of view of nonlinear dynamical theory. The analyzed flow is a time-periodic cellular convection in the two dimensional plane system. The effect of molecular diffusion is neglected in order to investigate the mechanism of mixing performed only by convection. The mixing processes can be classified into three steps. In the initial stage, the mixing pattern and the fluid exchange between the cells are determined by the geometric shapes of the lobes, which are composed of stable manifolds and unstable manifolds near the cell boundaries. In the next stage, the chaotic motion of fluid plays an important role in the construction of the fine structure in the lobes. The mixing pattern in the final stage is controlled by the geometric shape of the outermost KAM curves in the cells. © 1999, The Society of Chemical Engineers, Japan. All rights reserved.

Power numbers of several large two-blade paddle impellers in stirred vessels with dished bottoms were measured for a wide range of Reynolds numbers. Mixing patterns of these impellers with dished bottoms were observed for a wide range of Reynolds numbers by using a decolorization method based on the reaction between sodium thiosulfate and iodine. The power numbers of these impellers can be correlated with the modified correlation of Kamei et al. A relationship was established between the power number diagram (N-p-Re diagram) and the shape of the isolated zone. At low Reynolds numbers, complicated isolated zones were observed, while a cylindrically rotating isolated zone was not observed.

In a laminar flow in a mixing vessel, the velocity distribution is decided deterministically. When a blade rotates at a constant speed in a vessel, the velocity has perfect time-periodicity. In this convective mixing, there are definite rules controlling the fluid motion, and they are repeatedly applied. This mixing process is considered to be a deterministic process for which templates exist, and by the repeated use of them the mixing pattern is gradually develops. These templates are the time-invariant streaklines and the streak surface made by their assembly. The various forms of mixing blades and the use of baffles determine the curvature of the streaklines and the undulation of the streak surface as their assembly. Their deformations enhance fluid mixing in various manners. This study focuses on the geometry and the deformation of streaklines and the streak surface are focused. Through this, the mechanism of laminar fluid mixing in a mixing vessel and its enhancement effects on fluid mixing are clarified.

The power consumption of several wide-paddle impellers developed by mixer companies in Japan was measured over a wide range of Reynolds number, from laminar to turbulent flow regions. The power consumption of all wide-paddle impellers examined could be correlated by using Kamei and Hiraoka's expressions with the coefficients modified in this work.

The flow system in an agitated vessel is extremely complex because it is time-dependent, three-dimensional and spatially unsymmetric. Therefore, many questions on the mechanism of fluid mixing remain unsolved. In two-dimensional laminar mixing caused by chaotic flow, stable and unstable manifolds play important roles in the analysis of the fluid mixing. These invariant manifolds make the invariant structure controlling the mechanism of fluid mixing and act as the template of the mixing pattern. However, we do not know whether a similar invariant structure also exists in three-dimensional flow systems. In this study, we analyzed the mechanism of laminar fluid mixing in a three-dimensional agitated vessel with a two-blade paddle impeller, focusing on the particular streakline that grows from the tip of a blade and acts like an unstable manifold. On the basis of a visualizing experiment and numerical simulation with a simple flow model, we showed that this streakline is closely concerned with the formation of mixing pattern, and its strong stretching and folding near the side wall of the agitated vessel give rise to laminar global fluid mixing.

Because flows in a stirred tank are complicated by rotating blades and baffles, the mechanism of fluid mixing is difficult to analyze. The pathlines of fluid particles in this system are characterized by unsteadiness, threedimensionality and a lack of symmetry. However, the flow field does not necessarily involve the same complexity as the pathlines. In this study, we propose a simplified flow model of the complex flow motion in a stirred tanks, in which the flow velocities are expressed as a linear combination of elementary flows. By tuning the parameters contained in the model equations, changing the combination and relative intensities of the components, we were able to simulate flows corresponding to various shapes, numbers and positions of blades and baffles. This simplified flow model is useful for finding the elementary flow essential to fluid mixing in a stirred tank and elucidating the mechanism of mixing.

The difference in power consumption between dished-bottom and flat-bottom mixing vessels were investigated. In turbulent mixing vessels with standard baffle conditions and a radial flow type impeller, a difference of up to 20% in power consumption was found between the dished and flat bottoms. In vessels with pitched blade paddle and propeller type impellers and non-baffled vessels showed the same power consumption regardless the bottom geometry.

Mixing performance at unsteady speed within a single revolution was studied. Because the location of the vortices centers varied, the centers of stagnant domains of doughnut shape that are formed in laminar flow disappeared and the mixing time decreased drastically. For conventional impellers operating in laminar flow, the unsteady speed mixing technique was found to be much more effective than the steady speed mixing. The study confirms that asymmetric impellers are very useful in laminar mixing vessels.
