Descrição da secagem de placas cerâmicas por meio de um modelo de difusão

Abstract: O objetivo deste trabalho foi estudar o transporte de água, através do modelo da difusão líquida, em placas cerâmicas que podem ser usadas como revestimento de alvenaria, bem como apresentar um algoritmo de otimização baseado no método inverso. Para atingir os objetivos o algoritmo apresentado foi acoplado à solução analítica da equação de difusão, possibilitando determinar os parâmetros de processo a partir dos dados experimentais da secagem das placas. A condição de contorno empregada foi a de terceiro tipo … Show more

“…For a diffuse model to be used in the description of the kinetics of drying of a product, the diffusion equation must be resolved. The solution for the diffusion equation, in various situations of interest, requires the need to establish a hypothesis for the physical description (Silva et al, 2013). Besides the mathematical settings of the drying curves, the values from the effective diffusivity and energy activation are also fundamental for the project and the construction of drying equipment (Celma et al, 2009).…”

“…Moreover, models involving convective boundary condition is better to describe the drying process of tiles, since there is always resistance to mass flow on the surface of the product [19]. Various studies adopt the convective boundary condition for the description of drying processes [3,20,14].…”
