This publication aims to investigate conjugate heat and mass transfer around a clothed virtual manikin. This research can be performed at different scales: (1) at material scale where a piece of textile is investigated in 1D or 2D space or (2) at system level where a clothed cylindrical body (2D) or a complete manikin (3D) is modeled. The work is based on previous methods and results from ...

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 ...

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 ...

Pyrolysis is a key step in the conversion of carbonaceous materials into useful products. In this study, we investigate the pyrolysis of asphaltene and oil shale, both experimentally and numerically. COMSOL Multiphysics® software is used to model the combined effects of fluid flow in porous media, mass transfer of species, heat transfer, and reaction kinetics. Gas evolution and the porosity ...

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 ...

Electrochemical flow cells have found widespread use in analytical chemistry due to their short response time, high sensitivity and selectivity. The geometrical flexibility and therefore, the ease of coupling the electrochemical to other experimental techniques has attracted considerable interest for applications in electrocatalytic research as well. Such coupling is far more cumbersome with the ...

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 ...
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. ...

Experiments have been conducted with water at velocities from ~0.015-0.77 m/s to determine the permeability of 50 mm thick commercially available 30, 40, 50 and 80 Pores Per Inch (PPI) Ceramic Foam Filters (CFF) used for liquid metal filtration. Measurements were made using two different setups, for use with the Forchheimer equation: 49 mm \"straight through\" and 101 mm diameter \"expanding ...
