When Precise Numerical Predictions Come to the Rescue of Liquid Lubrication

J.-D. Wheeler [1], V. Bruyere [1], P. Namy [1],
[1] SIMTEC, Grenoble, France

Whereas some bearings designed in the 19th century are still working properly nowadays, some others which were recently designed encountered premature failures. Tribological applications, such as journal bearings or rolling element bearings, are generally ruled by complicated ... Read More

Experimental and Modeling Study of the Filtering Capacity of Green Wall Species

T. Ysebaert [1], S. Denys [1], G. Walpot [1],
[1] University of Antwerp, Belgium

Air pollution caused by particulate matter (PM) is one of the most severe issues in urban environments. Urban green infrastructure (UGI), in particular green walls, have been proven to be capable of capturing PM via deposition on leaves. This phenomenon was assessed by numerical ... Read More

Energy Harvesting in a Fluid Flow Using Piezoelectric Materials

M. Curatolo [1], M. La Rosa [1], P. Prestininzi [1],
[1] Roma Tre University, Rome, Italy

Energy harvesting from a fluid flow using piezoelectric materials is a relatively recent topic that has been investigated experimentally and numerically [1, 2]. Its possible application in natural water currents represents an interesting strategy to easily harvest renewable energy from ... Read More

Adaptive Mesh Refinement: Quantitative Computation of a Rising Bubble Using COMSOL Multiphysics®

T. Preney [1], P. Namy [1], J.-D. Wheeler [1], ,
[1] SIMTEC, Grenoble, France

The mesh is a key component in numerical simulations as it represents the spatial discretization of the model geometry. To accurately measure the variation of the unknowns, a relevant mesh should have a high density of degrees of freedom in regions where the norm of the gradient of the ... Read More

Simulation of Fluid Flow in an Artificial Soiling Device

E. Klimm [1], S. Kochersperger [1], K.-A. Weiss [1],
[1] Fraunhofer Institute for Solar Energy Systems, Freiburg, Germany

Solar systems are used around the world, especially in sunny and dry regions, to convert radiation energy from the sun into electricity or heat. Soiling, as dust deposition onto surfaces is commonly called, hinders this conversion of the solar energy by blocking of the incidenting light. ... Read More

Virtual Prototyping of UV-LED Based Point-of-Use Water Disinfection Unit

P. V. Christensen [1], P. Juul [2],
[1] Virtual Water Technology, Silkeborg, Denmark
[2] Liqtech Systems, Hobro, Denmark

Water disinfection using UV light is a well-known technology. Conventionally, mercury based cylindrical lamps are used, however, recently LED based UV lamps have emerged on a commercial scale. These devices hold several advantages compared to the conventional lamps, e.g. being mercury ... Read More

Modeling the Swirling Flow of a Hydrocyclone

B. Chine' [1], F. Concha [2], M. Meneses [3],
[1] Costa Rica Institute of Technology, School of Materials Science and Engineering, Cartago, Costa Rica
[2] Departamento de Ingeniería Metalúrgica, Universidad de Concepción, Concepción, Chile
[3] Costa Rica Institute of Technology, School of Industrial Production Engineering, Cartago, Costa Rica

Hydrocyclones are industrial devices used as processing units in fluid and particle technology. A hydrocyclone is an apparatus consisting of a cylindrical or a cylindrical-conical body with a tangential or involute entrance to admit the fluid inside. There are also two opposite exits, ...

Investigation of the Flow Characteristics of an Aerosol Mixing Facility

S. Horender [1], K. Auderset [1], K. Vasilatou [1],
[1] METAS, Bern, Switzerland

The measurement and regulation of particulate matter to improve outside air quality advanced a lot over the last decades. This also made it necessary to develop primary standards for calibrating these measurement systems and in future the composition of relevant aerosols will be taken ... Read More

CFD Based Optimisation of a Laboratory Scale Silo

A. Egedy [1], A. Rado [1],
[1] University of Pannonia, Faculty of Engineering, Veszprém, Hungary

The flow simulation of solid, particulate materials is still challenging, even though estimations show that three-quarters of products and raw materials are present as granules form in the industry. We can think of grain in the agriculture, raw materials of the glass industry, granulated ... Read More

Flow Optimization of a MVHR Combined with an Exhaust Air Heat Pump by Means of CFD Simulation

F. Ochs [1], M. Bianchi Janetti [1], M. Romani [2],
[1] University of Innsbruck, Unit Energy Efficient Buildings, Austria
[2] Galletti Group, Italy

In the framework of the Austrian FFG project SaLüΗ!, a compact mechanical ventilation system with integrated micro-heat pump was developed. The aim was a high level of prefabrication and a compact design allowing for installation also in small flats, e.g. into the façade. Due to the ... Read More
