摘要: A mathematical model is chosen and a finite-difference algorithm developed to describe the drying of agro products in batch fluidized bed. The discretized according implicit scheme for two particle geometries: sphere chip. system algebraic equations solved using tridiagonal matrix (TDMA). Stability convergence numerical are analyzed by variation time step mesh size, finding computer savings when nonuniform space steps boundary conditions three nodal positions. Obtained results compared with from literature experimental data potato chips drying, concluding that describes phenomena correctly.
