Frictional shear thickening in suspensions: The effect of rigid asperities

  title={Frictional shear thickening in suspensions: The effect of rigid asperities},
  author={Adam K. Townsend and Helen J. Wilson},
We study non-Brownian suspensions under steady shear flow. In concentrated suspensions, we are trying to reproduce the shear thickening phenomenon seen in, for example, cornstarch. We investigate the effect of different frictional contact models. When contact acts to impose a fixed minimum separation between particles, there is a strict upper bound to the viscosity predicted by simulations. We deduce that soft or compressible contacts are a critical component of the strong shear thickening seen… CONTINUE READING
