Two-component adhesives are commonly used for sealing and joining in transport applications for mechanically highly stressed connections. At the Chemnitz University of Technology an innovative system technology for the user-friendly, wireless and energy-efficient processing of two-component adhesives with electrical drive is developed. In this context, the simulation-based layout of main ...

Viscous fingering (VF) instability has been extensively studied over past several decades in the context of various industrial, environmental and chemical processes. We try to model miscible VF at pushed or pulled interfaces using COMSOL Multiphysics®. We study the effect of the positive and negative log-mobility ratio on the fingering instability. Numerical simulation has been performed in 2D ...

Metal foams are interesting materials with many potential applications. They are characterized by a cellular structure represented by a metal or metal alloy and gas voids inside (Fig.1). A common metallic cellular material is aluminum foam which can be produced metallurgically by heating a precursor, made of aluminum alloy and TiH2 as foaming agent, in a furnace. In this case, the foaming ...

Introduction: Lithospheric delamination beneath the western U.S. is believed to be the driving mechanism responsible for the evolution of magmatic and topographic features observed at the surface in the western U.S.. This process requires hot asthenosphere to be in contact with the underside of cold sub-crustal lithosphere and believed to be initiated by the Yellowstone hot spot plume that due ...

Wine quality is strongly dependent on the operation parameters of the production process. In batch or fed batch reactors, the rotating velocity should be carefully controlled to avoid cellular stress and ensure adequate mixing of the mixture. Moreover, precise control of substrates concentration evolution and cellular growth, as well as efficient heat transfer, allows the production of high ...

As known, air quality in urban areas is dramatically affected in particular by the noteworthy presence of respirable suspended particulate matter (such as PM2.5), nitrogen oxides (NOx), carbon monoxide (CO) and hydrocarbons (HC), which are mainly due to traffic-induced emissions. On the other hand, it is also known that vegetation can help restoring the environmental quality of dense urban areas ...

In this work, we present a mathematical model formulated to simulate the mechanical behavior of articular cartilage. Biological tissues of this kind can be modeled as fiber-reinforced porous media, filled with an interstitial fluid and exhibiting a process of remodeling . With this term, we refer to a class of dissipative phenomena which occur to modify the internal structure of the tissue ...

Dissolution of calcite plays an important role in various processes such as enhanced oil and gas recovery, CO2 sequestration, and groundwater transport for the drinking water production. Dissolution rates predicted by pore scale and continuum scale models are often faster than the observed laboratory rates (Molins et.al., 2014). This discrepancy suggests that the importance of pore scale ...

Over the last years, the concrete technology has progressed in order to improve the quality of its use and mechanical performances. Despite the technical development known in the context of concrete, the esthetic aspect remains weakly treated. Among the esthetic problems, there is the formation and dispersion of air bubbles (Bugholes) inside the concrete during the concreting process. An ...
On The Purification Of Waste Waters Using Multi-Bore Filters: Simulation Of A Long-Term Filtration Stage
Dipartimento di Matematica U. Dini, Universita' di Firenze, Italy
We present the progress of the simulation activity we are carrying out within the PURIFAST LIFE+ project. We first present the model we formulated to describe the macroscopic effects of the filtration process taking place in a multi-bore filter, focusing on the fouling phenomenon. In membrane-based filters the fouling phenomenon is the major reason of a decreasing filtration efficiency. ...
