Implementation of the modal technique to diffusion processes

It has always been a tremendous task for numerical analyses to solve non-linear partial differential equations. The modal technique presented in this paper, approaches the problem on his own specific way transforming the partial differential equation into two infinite sets of ordinary differential equations, very well suited to be solved on a hybrid computer. Since this technique gives rise to only differential equations, it can be classified as a continuous time continuous space method. Application of this technique to the moisture-flow equation shows that this method gives extremely good results, which are in close agreement with experimental data.
