Shear thickening fluids and their applications

Minghai Wei et al.

Summary: This paper provides a comprehensive review of shear thickening fluids (STFs), including their basic properties, classification, and rheological mechanism evolution. It discusses the factors influencing the shear thickening behavior of STFs and presents several computational models. Furthermore, it summarizes the research progress of STF-based composites in various fields and explores the applications of STFs in energy dissipation.

Structure of propagating high-stress fronts in a shear-thickening suspension

Vikram Rathee et al.

Summary: We directly measured the stress at the boundary of a shear-thickening cornstarch suspension and found persistent regions of high local stress propagating in the flow direction. The structure of these propagating fronts was determined, including the profile of boundary stress and the nonaffine velocity of particles. We also measured the relative flow between the particle phase and the suspending fluid and found it to be highly localized to the fronts and changing direction across the front. These fronts are composed of a localized region of high dilatant pressure and low particle concentration.
