Mathematical Modeling and Numerical Techniques in Drying Technology

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. Drying of granular and particulate solids: modelling heat and mass transfer in coupled systems during absorption and desorption; finite element modelling of grain drying; a mathematical model for constant and intermittent batch drying of grains in a novel rotating jet spouted bed; theoretical study of heat and mass transfer during frying of granular products; modelling convective drying of granular materials application to natural rubber. Miscellaneous applications: mathematical modelling of dielectrically-enhanced drying; mathematical models for the primary and secondary drying stages of the freeze-drying of pharmaceutical on trys and in vials; a model for superheated steam drying of particles in an impinging stream dryer; mathematical modelling of kiln and on-site drying of concrete; mathematical modelling and numerical techniques for multi-cylinder paper dryers.
