Freeze-drying is a popular method of producing shelf stable particulate products and is of particular value for drying thermally sensitive materials (volatiles and biological based), which can be heat damaged by higher temperature methods, such as spray-drying. Porous structures are ... Mehr lesen
Surface aeration systems are used in the wastewater treatment industry for the transfer of oxygen in the activated sludge process. These systems are capital intensive and also require a significant amount of energy to operate. Scale-up and design of these systems is largely empirical, ... Mehr lesen
In proper designs of hydrogen storage systems based on metal hydrides three processes are modelled and simulated: hydrogen flow (through the metal hydride bed), solid-state chemical transformation, and heat transfer (due to the highly exothermic chemical transformation). In this work, ... Mehr lesen
The model proposed by Schneider et al., for polymers is herein adapted in order to assess its suitability in elucidating the thixotropic behavior of aluminum alloys. The COMSOL Multiphysics program is employed to solve the inherent coupled mathematical problem, consisting in the ... Mehr lesen
A number of visualization experiments are carried out at the laboratory temperature with oil, brine and bacteria suspension for evaluating the performance of MIOR in a glass micromodel. The observations show the effects of bacteria on remaining oil saturation. The interfacial tension ... Mehr lesen
The modeling of sublimation form a rotating cylinder of solid naphthalene in a confined vessel has been performed by coupling the model of incompressible Newtonian fluid flow with the model of the dilute solutions. Preliminary a 2D axisymmetric system with swirl flow function for laminar ... Mehr lesen
A lixiviation-mechanical coupled model is developed for fiber reinforced concrete within this framework; both the influence of chemical degradation on short and long term mechanical behavior and the influence of mechanical loading on the diffusion coefficient can be considered. The ... Mehr lesen
The use of plasmas for the treatment industrial effluents provides a new alternative to the decontamination of wastewater. The strong oxidizing species (O,O3, OH) generated by the plasma, at room temperature, can oxidise organic pollutants present in the water. Our simulation deals with ... Mehr lesen
The performance of biofilters relies on the presence of a sufficient amount of water in the biofilter material. And breakdown of filtration performance is often caused by inappropriate water content. The present study focuses on the drying dynamics within such filter, which are modelled ... Mehr lesen
A bidimensional and pseudo homogenous model was proposed for the study of mass transfer in the bioadsorption process of chromium VI in the S-layer of immobilized Bacillus sphaericus in a packed column. The implementation of such a model in COMSOL Multiphysics will be explained in detail ... Mehr lesen
