This study reveals shear thickening in simple fluids using advanced simulations. Findings align with experiments, showing shear thickening and shear-induced ordering under different flow conditions.

Area of Science:

  • Fluid dynamics
  • Rheology
  • Computational physics

Background:

  • Non-Newtonian fluid behavior is crucial in many scientific and industrial applications.
  • Understanding microscopic fluid dynamics requires advanced simulation techniques.
  • Previous simulations often imposed constraints affecting flow profiles.

Purpose of the Study:

  • To investigate the non-Newtonian rheology of simple fluids using a novel simulation method.
  • To compare simulation results with experimental data from colloidal suspensions.
  • To identify shear thickening and ordering phenomena under various shear conditions.

Main Methods:

  • Utilizing nonequilibrium molecular dynamics (NEMD) simulations.
  • Employing a configurational thermostat that imposes no additional constraints on the flow profile.

  • Analyzing fluid behavior under steady and oscillatory shear conditions.

    • Main Results:

    • Observed shear thickening under steady shear, consistent with experimental results.
    • Identified strain thickening at low frequencies and shear-induced ordering at higher frequencies under oscillatory shear.
    • Demonstrated that shear thickening can occur independently of solvent effects.

    Conclusions:

    • The configurational thermostat provides a more accurate simulation of fluid rheology.
    • Simulation results validate experimental observations in hard-sphere-like colloidal suspensions.
    • The study advances the understanding of shear thickening and shear-induced ordering mechanisms in simple fluids.
