Granular suspension avalanches . II . Plastic regime

  title={Granular suspension avalanches . II . Plastic regime},
  author={Nicolas Andreini and Christophe Ancey and Ga{\"e}l Epely-Chauvina},
We present flume experiments showing plastic behavior for perfectly density-matched suspensions of non-Brownian particles within a Newtonian fluid. In contrast with most earlier experimental investigations (carried out using coaxial cylinder rheometers), we obtained our rheological information by studying thin films of suspension flowing down an inclined flume. Using particles with the same refractive index as the interstitial fluid made it possible to measure the velocity field far from the… CONTINUE READING
