Abstract
Polyatomic gas expansion under pulsed evaporation is considered in one-dimensional plane approach. A system of balance equations is constructed for gas cloud expansion. The obtained analytical solution allows to predict temporal evolution of the spatially averaged gas dynamic parameters, such as density, temperature, and velocity. The obtained results are in good agreement with results of direct Monte Carlo simulation. Based on the cloud parameters, the number of collisions per molecule during expansion is calculated. This number is used for approximate estimation of gas dynamic parameters (including vibrational temperature) for the case of incomplete vibrational cooling. Based on analytical regularities, analysis of experimental data on pulsed laser evaporation of aniline is performed. The calculated aniline vibrational temperature correlates well with the experimentally measured one.
