“…Figure 55 shows trajectories of several finite Stokes number particles localizing onto an attracting KAM tube in a 3D laminar flow. Predictions of what level of inertia will cause spontaneous localization of finite inertia particles have been quantified in recent experiments (Wang et al, 2014(Wang et al, , 2016. A direct consequence is that invariant curves no longer exist for the case of inertial finite-size particles.…”

This work reviews the present position of and surveys future perspectives in the physics of chaotic advection: the field that emerged three decades ago at the intersection of fluid mechanics and nonlinear dynamics, which encompasses a range of applications with length scales ranging from micrometers to hundreds of kilometers, including systems as diverse as mixing and thermal processing of viscous fluids, microfluidics, biological flows, and oceanographic and atmospheric flows.

“…The demonstration is shown in Figure 7. In this setup, the relatively simple setup consisting of a small unbaffled tank, an overhead stirrer and a liquid pump can allow removal of ∼75% purified liquid with minimal energy input (Wang et al, 2014(Wang et al, , 2016b.…”

The present paper provides an overview of the intensi cation of mixing processes with complex uids. First, mixing processes of rheologically complex uids and their design methodology are discussed. An example of process intensi cation of mixing with rheologically complex uids using a Couette-Taylor ow reactor is introduced. Second, the intensi cation of the mixing of a suspension with high concentration solids and a novel approach for solid-liquid separation using a stirred vessel are discussed. Finally, a perspective of the intensi cation of mixing processes with complex uids is summarized.

“…Liquid mixing are widely used processes in the majority of industry. On that account an assessment of flow behaviour in a stirred tank is the subject of numerous experimental and numerical studies (Virdung et al, 2008;Blais et al, 2016;Sharp et al, 2001;Long and Nong, 2017;Malik and Pakzad, 2018;Wang et al, 2016;Lamotte et al, 2018). The change in the quality of the mixing process can be achieved by changing many parameters for example: type and number of stirrer, rotation speed of stirrer, geometry of the tank or an orientation of the stirrer in the tank (Kresta et al, 2016).…”

In this paper the results of experimental research of flow pattern identification during mixing process using a stirrer in an off-center orientation in a rectangular tank were presented. The research applied Digital Particle Image Velocimetry (DPIV) technique. The velocity vector fields with regard to the stirrer orientation and rotational speed of the mixing process were determined and they were subsequently applied for identification and assessment of liquid flow pattern in a tank. Also the assessment of flow pattern by statistical non-uniform coefficient was introduced. The relation between the rotational speed of the stirrer and stirrer orientation for mixing performance were determined. The study demonstrated some lack of analogy in certain areas of liquid behavior during the mixing process in the tank with rectangular crosssection and circular cross-section.
