Abstract
The viscous stress in nonideal fluid lattice Boltzmann methods is investigated theoretically and by simulations. Three representative liquid-gas models are compared in a steady-state situation, where an analytical expression for the viscous stress in available. It is shown that, in the presence of nonideal fluid interactions or strong body forces the accuracy of the computed viscous stress depends strongly on the underlying model.
