Abstract:
An algorithm was developed for solving transient, three-dimensional, quasi-linear, inverse problems of heat and mass transport in nonhomogeneous agricultural products of irregular geometry. A numerical approach consisted of an optimization technique and a generalized finite element method, with the use of isoparametric, curvilinear, 3D-space elements, and a three-point recurrence scheme in time, absolutely stable, with iterative procedure to deal with the quasi-linearity of equations. A computer program was developed and the method was applied to estimate the moisture diffusion coefficient, and then to predict heat and moisture transport in individual corn kernels during drying.
