Two-dimensional anomalies of heat conductivity. A numerical method

you are: Two-dimensional anomalies of heat conductivity

Two-dimensional models of vertical sections with lateralnymi heat conductivity variations were investigated. For the decision it is required machine time to the little more than for the equation decision, in which the left part is equal to zero (i.e. For a stationary condition). The implicit scheme of a method of final differences with the variable direction, offered Rechfordom, was used for calculations on points of a two-dimensional vertical grid, and iterations were carried out until the stationary condition was reached.

During calculations such initial decision in which the temperature gradient at lateral edges of a grid is considered linear got out. The thermal stream through the bottom border of a grid was accepted to constants, and on a terrestrial surface (grid top) the temperature was considered constant and equal 0 °s; it was thus supposed, that no part of a thermal stream leaves through lateral borders of vertical section. It means, that the specified borders operate as an axis of symmetry for the models infinitely continued by reflexion on other party of each of these lines.
