Influence of different silica nanoparticles on drop size distributions in agitated liquid‐liquid systems [PDF]

, 2019
The impact of different silica nanoparticles on rheology, interfacial tension and drop size distributions in liquid‐liquid systems is determined experimentally. The particles vary in wettability and specific surface area.

Advanced numerical investigation of Saffman–Taylor instability in porous media with gas injection and rheological effects

Results in Engineering
The displacement of viscous fluids in porous media often leads to hydrodynamic instabilities, particularly the Saffman–Taylor instability, which reduces sweep efficiency in processes such as enhanced oil recovery, gas injection, and thermal management ...

Dynamic shear responses of polymer-polymer interfaces

, 2012
In multi-component soft matter, interface properties often play a key role in determining the properties of the overall system. The identification of the internal dynamic structures in non-equilibrium situations requires the interface rheology to be ...

Microdevices for extensional rheometry of low viscosity elastic liquids : a review [PDF]

, 2013
Extensional flows and the underlying stability/instability mechanisms are of extreme relevance to the efficient operation of inkjet printing, coating processes and drug delivery systems, as well as for the generation of micro droplets. The development of

Characteristics of stratified flows of Newtonian/non-Newtonian shear-thinning fluids

, 2017
Exact solutions for laminar stratified flows of Newtonian/non-Newtonian shear-thinning fluids in horizontal and inclined channels are presented. An iterative algorithm is proposed to compute the laminar solution for the general case of a Carreau non ...

Frictional dissipation of polymeric solids vs interfacial glass transition [PDF]

, 2006
We present single contact friction experiments between a glassy polymer and smooth silica substrates grafted with alkylsilane layers of different coverage densities and morphologies. This allows us to adjust the polymer/substrate interaction strength. We

Phase Coexistence of Complex Fluids in Shear Flow

, 1999
We present some results of recent calculations of rigid rod-like particles in shear flow, based on the Doi model. This is an ideal model system for exhibiting the generic behavior of shear-thinning fluids (polymer solutions, wormlike micelles, surfactant
