Two-dimensional electron temperature profiles in thermionic converters. Technical status report No. 79-0003 for the period July 1979
The electron temperature profile solution described by Timothy M. Smith in the report ENCOTH-TM79-0001 is generalized to two dimensions. The equations are written in cartesian coordinates used to solve structured electrode problems. An alaternate two-dimensional cylindrical geometry solution is trivially similar. The latter would be used to study departure from one-dimensional symmetry due to finite size electrodes and radial flows. The numerical method is described. The present work represents a partial solution of a complete two-dimensional transport, the purpose of which is the convergence of the proposed numerical approach. Also, the mathematical formulation of two-dimensional transport in electrical plasmas is given. The equations characterizing the two-dimensional transport and the electric field are selected, and a numerical method is proposed. (WHK)
