A comparison for different wall-boundary conditions for kinetic theory based two-fluid models

• We compared wall boundary conditions (BC) for kinetic theory based two-fluid models.
• Li and Benyahia BCs overestimate the granular temperature in the all sliding regime.
• Jenkin’s model reveals poor predictions of transition between sliding and no-sliding.
• Johnson and Jackson’s theory appears inappropriate in the all sliding regime.
• The most complete theory appears to be the BCs of Schneiderbauer et al. (2012a).
