Crack development and surface skin layers were utilized in model development. The drying cake had an extremely heterogeneous structure, with detail presented by constructed three-dimensional, tetrahedral volumetric grids. Drying modeling was conducted numerically by solving the conservation equations with assigned boundary conditions at so-constructed complicated volumetric structural model. ? 2010 Taylor & Francis Group, LLC. |
