It is shown that the monoenergetic diffusion equation in multi-region r-z geometry can be solved by the finite Fourier transformation method which has successfully been applied to x-ygeometry. In this method, a system of linear algebraic equations is derived for Fourier coefficients of fluxes and...

The general solution of the thermal diffusion equation for the case of a semi‐infinite two‐layer system that is heated with a localized cw laser beam of circularly uniform intensity profile is extended to times after the pulse is switched off. An application of that solution in the field of...
An approximation of the diffusion equation ut = auxx + buyy + cuzz + f(t, x, y, z, u) by the finite difference method with respect to the spatial variables x, y, z, leads to the system of ordinary differential equations U t = AU + F, whe... O Daman,T Styš - 《Journal...

The results are of interest in connexion with the electron density at great height in the F2-layer, and illuminate the nature of the diffusion equation. The electrodynamic drift causes the latitudinal peaks in electron density at constant height to move in towards the dip equator, and a ...
