Modeling of Transport Phenomena in Metal Foaming
Metal foams are interesting materials with many potential applications in engineering. Foamed metals or alloys include gas voids in the material structure with the real possibility to modify ad hoc their physical properties. Following our previous efforts aimed to simulate and study the ... Mehr lesen
Modeling of Energy Efficient Continuous Sterilisation of ABP from Food Wastes
Ohmic heating is a volumetric heating technology which can effectively process almost any pumpable fluid with extremely high energy efficiency (>95%). This is particularly useful for very thick fluids, those that burn on to hot surfaces and those with high solids content which would ... Mehr lesen
Modeling Deep-Bed Grain Drying Using COMSOL Multiphysics®
CFD simulations were carried out to predict the convective heat and mass transfer coefficients in the rice bed, and correlations were developed for the convective heat and mass transfer coefficients as a function of drying air flow rate. The developed correlations were used to extend the ... Mehr lesen
Integrated Solar Thermal Collector with Heat Storage
In this work, we study the design of a new integrated system for Solar Water Heating that combines the solar thermal energy collection (primary circuit) with the heat storage (secondary circuit) into the same device. We have performed different finite element method simulations using ... Mehr lesen
Heat-Accumulation Stoves: Numerical Simulations of Two Twisted Conduit Configurations
An important part of the society considers an increased share of renewable energies as an integral part of a strategy towards a sustainable future. As far as heat supply is concerned, this can be achieved using solar thermal collectors, borehole heat exchangers or trough the combustion ... Mehr lesen
Developments in a Coupled Thermal-Hydraulic-Chemical-Geomechanical Model for Soil and Concrete
This paper documents current status in the development of a coupled thermal-hydraulic-chemical-geomechanical numerical suite within COMSOL-MATLAB environment to address soil and concrete applications. The mathematical formulations are based on well-established continuum scale models ... Mehr lesen

The main topic of this paper is the development of an innovative tool that can be applied in a wide range of complex problems, to simulate, optimize and improve system design especially when dealing with huge numbers of parameters and constraints. The new methodology is obtained by ... Mehr lesen
Comparing Different Approaches for Moisture Transfer Inside Constructions with Air Gaps
A model for the conjugate simulation of heat and moisture transfer inside porous materials and fluid domains is implemented in COMSOL Multiphysics®. The results of this model are compared with those obtained through a simplified approach: the line-source approach. The models are both ... Mehr lesen
Combustion Study of DDGS Char from Steam-O2 Blown CFB Gasifier and Charcoal Using Thermogravimetric Analysis and COMSOL Multiphysics®
To obtain reliable kinetic data for the modeling of Dried Distiller’s grains with Soluble (DDGS) gasification using a 100 kWth steam-O2 blown circulating fluidized bed (CFB) gasifier, the combustion behavior of partially gasified residual DDGS char and pure charcoal as a comparison has ...
