Unsteady expansion of the vapor into vacuum from a flat surface was studied by the direct simulation Monte Carlo method. The vapor was considered as monoatomic gas (the model of hard spheres). The flow structure and its parameters in the ranges of flow modes from free-molecular to continual were investigated. The main attention is paid to the structure of the Knudsen and subsonic layers.
