Difusividade efetiva pelo método de diferenças finitas explícito bidimensional.

Abstract

The drying data of the samples of salted pieces of shark muscle (Carcharhinus limbatus), for three different air conditions and two different air velocities were treated using the bidimensional explicit finite difference method for the Fick’s second law to obtain effective diffusivity. The results, whitout shrinkage of sample, were compared with the effective diffusivities considering unidirectional analytical solution
