The notion of a Lagrangian Coherent Structure (LCS) is by now well established as a way to
capture transient coherent transport dynamics in unsteady and aperiodic fluid flows that are …

Mounting evidence suggests that fluid advection can effectively be studied by considering
special material surfaces, which are referred to here as Lagrangian coherent structures …

The flow field in a cylindrical container driven by a flat bladed impeller was investigated
using particle image velocimetry (PIV). Three Reynolds numbers (0.02, 8, 108) were …

The single-screw extruder with a perturbation baffle is a novel piece of equipment for
polymer processing, in which the polymer melts undergo complex chaotic mixing. In this …

The four-screw extruder (FSE) is a novel equipment for polymer processing. In this paper,
from a new viewpoint of Lagrangian coherent structures (LCS), two-dimensional fluid …

The internal mixer is an important devise for processing the polymer nanocomposites acting
as a chemical reactor. In this article, based on the computational fluid dynamics method, the …

Informally, dynamical systems are mathematical models that describe the evolution of a
point in its ambient space. The definition of a dynamical system in the semigroup formalism …

This work investigated the flow-field structure of the aerosol when spray pyrolyzing alkoxide
sols on the anode of fiber-shaped dye sensitized solar cell. The re-atomization of alkoxide …
