The hyporheic zone is defined as an area where water and matter exchange through the sand, gravel, sediments and other permeable soils under and beside streams. Its impact on the hydro-system function is determined by the proportion of subsurface biogeochemical reactions and the fluxes of water exchanging with the hyporheic zone and flowing through the porous sediments. The objective of our ...

In this paper we study the natural convection for Dual In-Line Memory Module (DIMM) systems. Numerical models are developed using COMSOL Multiphysics. The results, obtained for imposed ambient temperature and operative conditions (power supplied to the CPUs) were produced and complex fluid motion field could be detected.

"All models are inverse problems". This presentation gives some clues to how COMSOL Multiphysics, and its integration with MATLAB, can run models 'backwards'. A number of examples are shown to exemplify the collaboration between modeling, calibration and interpolation. --------------------------------- Keynote speaker's biography: Professor WBJ Zimmerman BScEng (Princeton), MSc PhD ...

Simulated moving bed (SMB) chromatography is a commonly used separation technology. It consists of chromatographic columns that are interconnected to a ring. The feedings and drains are changed cyclically so that a continuous separation is maintained. To find optimal operating conditions, the triangle theory is often used. This theory is based on a true moving bed (TMB). Therefore, it will only ...

A clothing system should offer the user a period of relatively comfort. However, changes in the ambient conditions over day affect the heat and mass transport in the system, influencing the user comfort perception. In order to gather information to allow the optimization of clothing systems, it is essential to understand the heat and moisture transfer occurring across multi-layer textiles. For ...
Multiphase Transport with Large Deformations Undergoing Rubbery-Glassy Phase Transition: Applications to Drying

Drying of biomaterials such as foodstuffs involves mass, momentum and energy transport along with large shrinkage of the porous material, which have significant effects on their final quality. Foodstuffs exhibit non-linearity when undergoing large deformations that affect the transport process in a critical way. Thus, it becomes important to perform a two-way coupling of the multiphase transport ...

A two-dimensional mathematical model for the absorption and desorption of H2 in LaNi4.8Al0.2 was developed and experimentally validated. The model is composed of an energy balance, a mass balance and a momentum balance. These differential equations are numerically solved by means of the finite element method using the software COMSOL Multiphysics®. From a comparison between theoretical ...

In this paper, we present a mathematical model for simulating the mass transfer, during the osmotic dehydration of mango cubes. The mass balance equation for the transport of each constituent is established separately for intracellular and extracellular volumes but accounts for the mass exchange across the cell membrane and the shrinkage of whole tissue.

TAP (Temporary Analysis of Products) reactors are powerful instruments to study the kinetics of catalytic reactions. Their basic principle, exposition of evacuated solids of interest to narrow pulses containing very small amounts of gases, and measuring the concentrations of outgoing molecules permits to study practical catalysts under the conditions approaching those of molecular beam ...
