Colloids and Suspensions

4.0K
Children at play often make suspensions such as mixtures of mud and water, flour and water, or a suspension of solid pigments in water known as tempera paint. These suspensions are heterogeneous mixtures composed of relatively large particles visible to the naked eye or seen with a magnifying glass. They are cloudy, and the suspended particles settle out after mixing. The suspended particles in a suspension settle out after some time of mixing. The separation of particles from a suspension is...

Area of Science:

  • Fluid Dynamics
  • Soft Matter Physics
  • Rheology

Background:

  • Vesicle suspensions exhibit complex rheological behavior under shear flow.
  • Previous studies relied on numerical and experimental methods to understand this behavior.

Purpose of the Study:

  • To analytically predict the time-dependent effective viscosity and normal stress differences for vesicle suspensions.
  • To investigate the influence of the viscosity ratio on rheological properties.
  • To derive a constitutive law for vesicle suspensions in arbitrary linear flow.

Main Methods:

  • Analytical examination of vesicle suspension rheology in linear shear flow.
  • Utilizing coupled nonlinear equations for vesicle orientation and shape evolution.
  • Derivation of exact analytical predictions for effective viscosity and normal stresses.

Main Results:

  • Exact analytical predictions for effective viscosity (η_eff), N1, and N2.
  • Demonstration of steady-state or periodic rheological responses.
  • Identification of shear viscosity minimum and cusp singularities at the tumbling threshold.
  • Derivation of a closed-form constitutive law for arbitrary linear flow.

Conclusions:

  • The derived constitutive law for vesicle suspensions differs significantly from classical models.
  • The viscosity ratio (λ) is a key parameter controlling rheological response.
  • Analytical predictions offer new insights into vesicle suspension dynamics.
