Résumé :

A one-dimensional lattice gas model is used to study the interaction of fluid flows with solid boundaries. Various interaction mechanisms are examined. Lattice Boltzmann simulations show that bounce-back reflection is not the only interaction that yield "no-slip" boundary conditions (zero velocity at a fixed wall) and that Knudsen-type interaction is also appropriate. © 1991.
