Abstract
An alternative approach to the finite element method has been developed to simulate freezing and thawing processes in irregular two-dimensional systems. A code employing boundary-fitted grids (BFG) was implemented in a numerically conservative form (control volume formulation). The proposed model was satisfactorily checked against experimental data obtained with minced meat and Tylose. The accuracy of the BFG method is similar to one obtained by finite elements but shorter computer times and simpler codes were employed.
