Dynamics of Self-Propelled Janus Particles in Viscoelastic Fluids. [PDF]
Physical Review Letters, 2016 We experimentally investigate active motion of spherical Janus colloidal particles in a viscoelastic fluid. Self-propulsion is achieved by a local concentration gradient of a critical polymer mixture which is imposed by laser illumination.

Electrokinetic effects in helical flow of non-linear viscoelastic fluids
, 2020 Helical flows of complex fluids through annular regions have been studied extensively for their large spectrum of applications ranging from extrusion to mud drilling. Such flows include an axial flow in the presence of cylinder rotations, and they become

Viscoelastic Particle Focusing and Separation in a Spiral Channel
Micromachines, 2022 As one type of non-Newtonian fluid, viscoelastic fluids exhibit unique properties that contribute to particle lateral migration in confined microfluidic channels, leading to opportunities for particle manipulation and separation.

Optimization of the Production of Rubber Compounds Using Mathematical Models
Advanced Engineering Materials, EarlyView.Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

Review of Single Bubble Motion Characteristics Rising in Viscoelastic Liquids
International Journal of Chemical Engineering, 2021 The emphasis of this review is to discuss three peculiar phenomena of bubbles rising in viscoelastic fluids, namely, the formation of a cusp, negative wake, and velocity jump discontinuity, and to highlight the possible future directions of the subject ...

Soft Mechanical‐Electrical Logic Using Liquid Metal‐Filled 3D‐Printed Architectures
Advanced Engineering Materials, EarlyView.We present 3D‐printed soft mechanical–electrical logic elements that use liquid metal–filled silicone tubes actuated by thermoplastic polyurethane/polylactic acid (TPU/PLA) architectures to produce Boolean operations. Complementary normally open and normally closed unit cells perform repeatable binary transitions and can be combined into more complex ...

Particle Focusing under Newtonian and Viscoelastic Flow in a Straight Rhombic Microchannel
Micromachines, 2020 Particle behavior in viscoelastic fluids has attracted considerable attention in recent years. In viscoelastic fluids, as opposed to Newtonian fluids, particle focusing can be simply realized in a microchannel without any external forces or complex ...

Animating Viscoelastic Fluids. [PDF]
, 2011 In this thesis we describe a technique for animating the behavior of viscoelastic fluids such as mucus, liquid soap, pudding, toothpaste, or clay, that exhibit a combination of both fluid and solid characteristics. The technique builds upon prior Eulerian methods for animating incompressible fluids.
