The NARVA 55917 is a high-precision special lamp produced in Germany by the lamp manufacturer vosla GmbH. It is representative of a wide range of high-quality pin base lamps for medical and analytical equipment such as microscopes and analyzers for blood and water samples. Furthermore, special lamps such as these are used in optical measuring instruments (spectrometers, photometers, etc.). NARVA lamps meet the strictest quality criteria in the medical sector. This means that they can be used in operating theaters, in medical devices and in diagnostics.

The 1D measurement device “light” serves for the length measurement of long, narrow workpieces in the productions environment. This product offers a cost-effective alternative exactly for such measurement tasks where a sliding calliper is too short and a measuring tape is too inaccurate. With the 1D measurement device “light”, linear dimensions can be gathered quickly and reliably in the simplest manner. Essential characteristics • Light-weight, cost-effective construction using high-quality components with deliberate • Universal modular system – the equipment can be individually arranged - measuring length from 950 mm to 3,850 mm in a variety of graduations - accuracy: ± (0,06mm + 0,02mm x L), L=measuring length in m - very easy to use - use-oriented configurable (workpiece supports, measuring equipment) - high-quality, robust Magnescale® measurement systems - optional PC-/Printer Interface RS232/USB - optional workbench (also mobile) and workplace equipment

The particle image velocimetry (PIV) is an optical noninvasive working flow velocity measurement method. The flow field is made visible by introducing into the fluid small buoyancy neutral particles – the so called tracers. The particle flow then is illuminated with the aid of a light sheet and recorded at two defined different times within a small time interval with a digital camera. Because the particle move within this time interval with the flow, one can calculate the particles velocity by knowing its path between the two moments of illumination. The result is a velocity vector field of the flow. Here, we assume that the particles are small and follow the flow without any slip. Compared to local methods like LaserDopplerVelocimetry (LDV) with the ParticleImageVelocimetry one can reconstruct a whole flow region An extension of ParticleImageVelocimetry is the combination of PIV with thermometry (PIV/T).

For the generation and production of a spray the knowledge of information like the desired droplet size and its distribution is of fundamental importance. In order to characterise a spray correctly, one has to know the droplet size distribution of the droplets, which were generated out of a given liquid. In many applications it is desired to produce very small droplets. For the design and lay out of inhalers for example, it is necessary to achieve droplet sizes not larger than approximately 10 μm to be absorbed by the lungs. When one designs an atomisation nozzle in view of the desired droplet size distribution, one has to make sure via measurements, that the nozzle is really able the produce the expected droplet size distribution within an acceptable uncertainty range. Besides the droplet size distribution, the droplet velocity is an important parameter since it is a measure of the droplet momentum.

A further area of activity of Suvis is the development and application of modern numerical methods for the calculation (prediction) of flows using CFD in industry, science etc. Our employees are especially trained in view of technical applications of numerical flow simulations. Within the recent years we conducted several projects in the area of multiphase flows. We dealt with applications in the optimisation of processes in chemical engineering, the transport of particles, gas cleaning and particle separation from gases and liquids, and the calculation and optimisation of cyclone separators. We apply powerful commercial software tools like grid generators in order to generate numerical grids using CADdata in a short time for even complex applications. Also, for flow calculations and the evaluation of 3D flow fields we apply powerful software solutions. Furthermore, for certain individual problems we apply codes we have developed our selves.
