Abstract
In this work, we consider a semi-infinite expanse of a rarefied gas bounded by its plane condensed phase on which evaporation takes place. The analysis is based on the BGK model derived from the Boltzmann equation. In particular, the strong evaporation problem is considered, where nonlinear aspects have to be taken into account. We present the complete development of a closed form solution for evaluating density, velocity and temperature perturbations. Numerical results are presented and discussed.
