“…While the use of a three-dimensional numerical solution coupled to an optimizer can take several hours to determine D and h (Silva et al, 2012b), with a three-dimensional analytical solution and the optimization algorithms presented here this time is reduced to few minutes (Silva et al, 2012c). On the other hand, the use of these algorithms coupled to one-dimensional analytical solutions reduces the optimization time to few seconds (Silva et al, 2009).…”

“…This is the advantage of diffusive models when compared to empirical models; the empirical ones do not provide such distributions. Besides, they do not keep reliable physical consonance with the drying process [13]. 3.4 Comparison between one-, two-and three-dimensional models…”

“…In order to implement a better description of mass flow resistance on the surface of the product, some studies on diffusion have considered the boundary condition of the third kind, which permits one to obtain parameters such as the convective mass transfer coefficient. Silva et al (2013c) have considered the condition of the third kind for the three-dimensional diffusion equation in order to provide a detailed description of the removal of water from coconuts cut up in rectangular slices, along a process of osmotic dehydration followed by convective drying. An analytical solution was used for the three-dimensional diffusion equation coupled with an optimizer in order to determine physical parameters.…”
