... and the gray LBM eventually predicts an effective thermal conductivity value of zero for a film of vanishing thickness. This behavior is consistent with the gray LBM formulation, in which the transition to ballistic transport is a function of a single parameter, the Knudsen number. Subcontinuum effects start...
