A Multiphysics Approach to Fundamental Conjugate Drying by Forced Convection

M. de Bonis, and G. Ruocco
DITEC, Universitµa degli studi della Basilicata, Campus Macchia Romana, Potenza, Italy

Heat and mass transfer involved in drying is studied by using COMSOL 3.4. The effect of air temperature on the performance of the drying process applied to fresh food slices is scrutinized. COMSOL’s flexible formulation is exploited by using special drying kinetics for the substrate, and by including a treatment of the dependence of the properties upon the residual moisture content. The model ...

Investigation of Natural Convective Air Flow Field through Comb Channels

R. Umhack, M. Rainer, M. Tamerle, and G. Hillmer
Process-, Environmental- and Bio- technology, MCI - University of Applied Sciences, Innsbruck, Austria

A new type of radiator with a package of combs, to gain a larger area for heat exchange, instead of trapezoidal convector plates, is investigated. The main aim is to find the optimal comb diameter. To solve this problem, CFD (computational fluid dynamics) with COMSOL Multiphysics is used. A chart showing radiator power was produced, which includes radiator power for different temperatures and ...

Numerical Modelling of Electrophoresis Applied to Restoration of Archaeological Organic Materials

Restoration of archaeological materials from oceans is a major activity of Arc’ Antique. Organic materials such as wood, tissues, leathers, papers and ceramics found in sea water are always impregnated with salts. Rinsing such archaeological objects with pure water to extract the salts takes too long, so electrophoresis was used to improve the salt extraction. The objective of this ...

Study of Thermo-Electrical and Mechanical Coupling During Densification of a Polycrystalline Material Using COMSOL

Spark Plasma Sintering (SPS) is a promising rapid consolidation technique that allows a better understanding and manipulation of sintering kinetics and therefore makes it possible to obtain polycrystalline materials (ceramic or metallic) with tailored microstructures. A numerical simulation of the electrical, thermal and mechanical coupling during SPS is performed. Equations for conservation for ...
