Kinetic theory of discontinuous shear thickening of a moderately dense inertial suspension of frictionless soft particles
arXiv:2207.05752 · doi:10.1093/ptep/ptaf008
Abstract
We demonstrate that a discontinuous shear thickening (DST) can take place even in a moderately dense inertial suspension consisting of frictionless soft particles. This DST can be regarded as an ignited-quenched transition in the inertial suspension. An approximate kinetic theory well recovers the results of the Langevin simulation in the wide range of the volume fraction without any fitting parameters.
