On boundary conditions construction for 1D transport equation according to quasidiffusion and frozen coefficients methods

In this article the process of boundary conditions construction for 1D transport equation is described. The boundary conditions construction is based on averaging transport equation according to quasidiffusion [1] and frozen coefficients [2] methods which alleviate transport equation solving by reducing its “dimensionality”. The development of the appearing boundary quasidiffusion and frozen coefficients is given. The presented way of boundary conditions construction is implemented in the program package RADIAN [3] for simulation of 1D radiative gasdynamics problems.
