A linearized kinetic formulation including a second-order slip model for an impulsive start problem at arbitrary Knudsen numbers

We investigate the time evolution of an impulsive start problem for arbitrary Knudsen numbers ($\hbox{\it Kn}$) using a linearized kinetic formulation. The early-time behaviour is described by a solution of the collisionless Boltzmann equation. The same solution can be used to describe the late-time behaviour for $\hbox{\it Kn}\,{\gg}\,1$. The late-time behaviour for $\hbox{\it Kn}\,{
