Textiles et tissus à usages techniquesIndex. décimale : 677 Textiles Résumé : A seemingly unending series of heat records and more heavy rain events are the effects of climate change, with fatal consequences for cities and their inhabitants. Flooding and urban heat islands cause more than just the population to suffer ; building and infrastructure damage due to flooding costs billions of euros in Germany alone every year. A possible solution has now been found at the Institute for Lightweight Structures and Conceptual Design (ILEK) at the University of Stuttgart/Germany : Lightweight, textile facade elements called HydroSkin absorb rainwater and release water during hot spells to cool building interiors and urban spaces through evaporation. Note de contenu : - Fig. 1 : The core element of HydroSkin is a spacer fabric, 2 textile layers which are kept apart by threads and thus well-ventilated
- Fig. 2 : The lightweight textile facade elements HydroSkin absorb the rainwater that hits the building envelope at an angle and release water in hot periods in order to cool the building interior and urban space naturally through evaporation
- Fig. 3 : Currently, the hydroactive facade elements are being tested under actual weather conditions on the University of Stuttgart's D1244 high-riseEn ligne : https://drive.google.com/file/d/1T2G9bt-Z-xZdodrH1suVzt73FW7LUfw_/view?usp=drive [...] Format de la ressource électronique : Permalink : https://e-campus.itech.fr/pmb/opac_css/index.php?lvl=notice_display&id=39471

ThermocinétiqueIndex. décimale : 668.4 Plastiques, vinyles Résumé : The striving for injection molded parts with an increasing functional density leads to more complex molds, which are more and more designed with injection molding simulation. Nowadays, software allows the operator to analyse not only the filling stage, but also the thermal activity within both, the mold and the part during the whole process cycle. However, commercial simulation software for injection molding does not offer the visualisation of the flow of the temperature control medium to get a reliable determination of the pressure drop and the local heat transfer coefficients (HTC). For this reason the potential of an exact implementation of the local HTC „towards the temperature control medium, for improving the prediction precision of the thermal design, has been analysed at the Institute of Plastics Processing (IKV), Aachen. In order to use prior calculated HTCs from Computational Fluids „Dynamics (CFD) simulations inside injection molding simulations, the development of an analogous model was required. An isolation layer between cooling channel and mold was therefore introduced, which allows to set a local heat transfer by varying the geometric dimensions of the layer. Several cooling channel layouts, which differ in geometric aspects (e.g. bends, diameter or fragmentation/consolidation of parallel channels) were studied with this set-up.

Systèmes de refroidissementIndex. décimale : 668.4 Plastiques, vinyles Résumé : 2-Component Water Pump Housing - Under the engine hood numerous densely packed subassemblies and media piping dominate the scene. Nevertheless the ever increasing system integration is the governing principle of all modern motor designs. An example is the motor cooling system. Here, an externally mounted cooling water pump became an integral part of the motor housing. But the environment places high demands on the plastic components. Note de contenu : - The road to success
