Offers information necessary for the development of mathematical models and numerical techniques to solve specific drying problems. The book addresses difficult issues involved with the drying equations of numerical analysis, including mesh generation, discretization strategies, the nonlinear equation set and the linearized algebraic system, convergence criteria, time step control, experimental validation, optimum methods of visualization results, and more.
List of contents
Fundamentals: a synopsis of the strategies and efficient resolution techniques used for modelling and numerically simulating the drying process; the use of macroscopic equations to simulate heat and mass transfer in porous media; modelling and simulating simultaneous liquid and vapour transport in partially saturated porous materials. Drying wood: high- temperature kiln drying of softwood timber: the role of mathematical modelling; modelling the effect of heterogeneity on wood drying; a numerical prediction of the effect of airflow and wet bulb temperature on the stress development during convective wood drying.
