文摘
- •
Statistical treatment of the collisional dynamics of the hard-sphere system.
- •
Inclusion of distributions as admissible solutions of the Liouville equation.
- •
Collision boundary conditions used in past literature are physically inconsistent.
- •
New modified collision boundary conditions are proposed and proved to apply.
- •
The result is relevant for the study of dense or locally-dense gases and fluids.
