Laser cladding is an additive manufacturing process, where a laser beam creates a melt pool, into which powder is fed from a powder nozzle. Due to the feed motion of the laser beam and the powder nozzle relative to the workpiece, coatings and 3D parts can be deposited, which consist of ... En savoir plus
Black-oil simulators are commonly used in petroleum reservoir engineering for the prediction of oil production, especially during the earlier stages of oil-field exploitation, while also serving to guide pressure maintenance strategies in the longer term. Such models account for fluid ... En savoir plus
To assess the safety deep geological repositories for nuclear waste, it is important to have a clear understanding of groundwater flow at the interface between the storage vault and the fractured rock. Traditional approaches for modelling groundwater often consider both the geological ... En savoir plus
Actual trends in lightweight construction and safety-relevant technologies cause an increasing demand for reliable design of joining connections. Increasing power density and compact design require dimensioning of joints with low safety factors. Thereby additional security measures are ... En savoir plus
Surface engineering is a key technology used in a wide range of sectors in industry. Among other techniques, it involves adding functionality to a surface. This can be performed by creating a specific topography to a surface using laser texturing. The objective of the work presented in ... En savoir plus
To receive a stable quality in the injection molding process in the view of mechanically and thermally highly stressed components made by reactive resin systems, it is necessary to understand the material state along the processing chain. Up to date no measuring technology is available ... En savoir plus
Of utmost importance in appliance design and manufacture are the features for protection from fire and for personal safety. Appliance engineers are continually in pursuit of better,longer-life appliances that will provide both lower cost to the consumer and lower energy consumption. ... En savoir plus
An injection moulding tool developed by the FH Bielefeld is being displayed in a thermally precise way by means of COMSOL Multiphysics®. The tool is tempered through heat pipes. The performance of heat pipes is experimentally determined and depicted in a function. The function ... En savoir plus
We modify a Tunnel Effect Microscope (STM) with the purpose of analyzing the local production of photons in the electrostatic junction during the image taking process. The novelty of this project compared to previous studies is that it is intended to be developed from the beginning as ... En savoir plus
Applications of mid-infrared photonic technologies are fueled by innovative advances in quantum cascade lasers, and other key optical components like MEMS gratings and fiber-optics. The integration of devices into optoelectronic packages for stable operation at high powers poses also ... En savoir plus
