Implication

Analysis reveals exact diffusion coefficients in granular gases under shear flow, highlighting differences from IHS results.

Key Points

  • Exact results show how mass flux depends on tensorial quantities due to shear flow characteristics.
  • The kinetic model reveals significant insights into diffusion in granular gases compared to prior approximations.
  • Two approaches are utilized: one with inelastic Maxwell models and another involving hard spheres under shear conditions.
  • The study includes phase diagrams of segregation showcasing qualitative agreement with previous inelastic hard sphere findings.
