Abstract: | The ADO method, an analytical version of the discrete-ordinates method, is used here to solve a heat-transfer problem in a
rarefied gas confined in a channel, as well as to solve a half-space problem in order to evaluate the temperature jump at
the wall. This work is an extension of a previous work, devoted to flow problems, where the complete development of the solution,
which is analytical in terms of the spatial variable, is presented in a way, such that, a wide class of kinetic models are
considered, in an unified approach. A series of numerical results are showed and different simulations are used in order to
establish a general comparative analysis based on this consistent set of results provided by the same methodology. In particular,
numerical results for heat-flow profile, temperature and density perturbations are obtained for channels (walls), defined
by different materials, on which different temperatures are imposed. |
