Making the invisible visible: Localization of dynamic flow phenomenaThe flow behaviour of the rotor blades of wind turbines is dynamically influenced by the environmental conditions, the condition of the rotor blades and the operating conditions of the wind turbine. The flow around the rotor blade is influenced by the tower... » more

Indirect optical geometry measurements with fluorescence particlesOptical measurement techniques enable fast and precise geometry measurements. However, the measurements are influenced by the optical properties of the measure-ment objects themselves. To enable measurements that are independent of the measurement object... » more

Evaluation of motion blur of thermograms taken with a drone.Thermographic flow visualization is used to evaluate the aerodynamic condition of rotor blades on wind turbines. When monitoring a wind turbine in operation by means of a drone-based measurement system, blurred images occur during the measurements, which are... » more

Investigations into the flow behavior of microparticle seedingsFlow measurements are of growing importance in many areas of the economy and society. Particularly with regard to sustainability and energy efficiency, the flow behavior of car bodies, wind turbine blades or aircraft must be perma-nently optimized. » more

Indirect optical geometry measurements with fluorescence particlesOptical measurement techniques provide fast and precise geometry measurements, however, only if sufficient light is reflected from the object surface to the photodetection unit. For this reason, specific measurement methods have to be developed for each type of... » more

Tool deflection measurement in incremental sheet forming using an optical multi-sensor systemThe innovative process of incremental sheet forming is associated with high form deviations resulting, among other things, from the deflection of the forming stylus. For this reason, the tool deflection has to be detected with an optical measuring system... » more

Spatially resolved temperature measurement in fluids using confocal fluorescence microscopyThe increasing demand for technical parts with micro dimensions increasingly requires the use of manufacturing techniques such as laser chemical manufacturing (LCM), whose non-contact material removal is based on a localized chemical reaction with an electrolyte... » more

Deformation measurements of lightweight gearsThe main objective of this work is to validate the design guidelines of first lightweight gear demonstrators by means of static and dynamic load tests. For this purpose, deformation measurements on statically or dynamically loaded lightweight gears are to be... » more

Flowmeasurement in grinding gapMetalworking fluids (MWFs) are used in grinding to reduce the heat generation of the abrasive process and to prevent thermal damage such as grinding burn. The heat transport of an active liquid cooling (forced convec-tion) is fundamentally known, but the cooling... » more

Surface characterization of gear teeth by means of lateral scanning white light interferometry (LSWLI)In order to comply with climate protection targets, the trend in industry is developing toward resource conservation and energy saving. In the case of gears, this trend can be implemented through constructive lightweight design, but also through optimization of... » more

Speckle roughness measurement on anisotropic surfaces"Speckles" are points of light that are created when rough surfaces such as paper, wallpaper or metals are illuminated with a laser. By statistically evaluating the speckle pattern (e.g. on the basis of its contrast), the roughness and other surface parameters can... » more
