SOLUTION ASYMPTOTICAL PROPERTIES OF A TRANSFER EQUATIONS IN NON-ONE-DIMENSIONAL LONGITUDINAL CYLINDRICAL FIELDS

Non-one-dimensional boundary-value problems for a monopower, stationary equation of the radiation transfer are considered in the paper aiming at the asymptotical theory development for the radiation transfer in longitudinal non-one-dimensional cylindrical regions. The development of algorithms and programs for the determination of deep regimes is also the aim of the paper. As a result typical boundary-value problems for longitudinal non-one-dimensional cylindrical regions have been constructed and investigated. Formulae for a deep regime far from sources have been obtained. The asymptotics existence has been proved. Test results (of high accuracy degree) in problems of deep regimes, results intended for the verification of numerical methods and non-one-dimensional programs, have been obtained. The paper results may find their field of application in theory and solution numerical methods for problems of the radiation transfer, in the verification of programs and methods, used in the transfer theoryAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
