Overview

Numerical simulation reveals how shear-thinning affects particle behavior in non-Newtonian fluids, suggesting design improvements for industrial applications.

Key Points

  • This research aims to understand the interactions between cylindrical particles and shear-thinning non-Newtonian fluids in flow conditions.
  • Used particle-resolved direct numerical simulation (PR-DNS) to analyze flow interactions.
  • Characterized fluid properties through the Carreau model.
  • Systematically studied effects of Reynolds number, aspect ratio, power-law index, Carreau number, and inclination angle on coefficients.
  • Found that shear-thinning properties lower drag, lift, and torque coefficients.
  • Noted that the impact of shear-thinning is more pronounced at low Reynolds numbers.
  • Identified larger aspect ratio particles exhibit higher drag, lift, and torque coefficients.
