However, sample 8 has a small thread diameter and screen thickness that decreased the pressure drop coefficient. The results obtained in this work show that the eleven screens can be classed in three groups, corresponding with the fibre density, with similar porosity and airflow properties (permeability and inertial factor).

The software allows to determine all the geometric parameters that characterize the screens, as thread diameter and distances between two adjacent threads in two directions, from the four coordinates that defined each pore.
Previously, an analysis images system, called EUCLIDES v1.1, was designed with MS Visual Basic 6.0 running under MS Windows, for the analysis of the screens samples images captured with a microscope.Ī geometrical characterization of the eleven screens materials was carried out using this software tool.

Last analyses were carried out by numerical simulations of airflow through insect-proof screens using a commercial fluid dynamics code based in Finite Element method (ANSYS/ FLOTRAN v8.0). The two first arrangements had the same principle, in that air was forced through the test samples in order to create a pressure drop.
The aim of the present study was to evaluate geometrical characteristics and airflow resistance of eleven different insect-proof screens by three different experimental procedures: equipment based in water-flow suction, low-speed wind tunnel, and CFD simulations.

The system ensures perfect projection quality at all times, even for such highly complex multiple projector setups.įurthermore, Kraftwerk Living Technologies integrated a customized, discrete, and powerful 12.4 audio system with high DSP power to match the client’s wish for high level entertainment. Based on the measurements done by the cameras and a virtual 3D model, the system slices the individual parts of the master content and warps, blends, and masks them automatically to one seamless projection on the screen surface.
Kraftwerk Living Technologies integrated a state-of-the-art automatic alignment system, featuring 13 cameras measuring the screen’s pixel-accurate geometry. To overcome this obstacle, the projectors are protected by massive outdoor housings with easy maintenance access. The major challenge was that the projectors are exposed to the sea air. The projection system features 18 high-performance projectors which have a combined total of 100,000 lumens of light output. On behalf of Falcon’s Treehouse, Kraftwerk Living Technologies designed and installed a projection system in a 20-meter long tunnel-shaped customized screen. What could be Kraftwerk Living Technologies’ contribution to a roller coaster? In this case it is the so-called “launch station” where the passengers start the ride enclosed in a launch tunnel with larger-than-life images of rays projected on a 270-degree enveloping screen.
