Equipment
Starting with empty offices and an empty small experimental hall the institute has a considerably and high-quality technical equipment by now. Powerful computers equipped with software for simulation purposes as well as standard office applications are employed here. For large simulations a highperformance computer cluster can be used.
For experimental work, the institute owns technical laboratory equipment in the research areas of fluid dynamics, air quality and thermal comfort. The standard measurement technique includes air temperature, surface temperature, humidity, pressure, illumination, CO2 and high sensitive pressure sensors.
The thermal sensation and comfort measurement instruments are complemented by a comfort sensor for the measurement of turbulence intensity and omni directional thermal anemometers with wireless communication enabling data logging from distance.
A two direction Laser Doppler Anemometer is used for accurate measurements of velocities. By use of a computer-controlled traversing mechanism, measurements can be made in a precise matrix of points. Entire flow fields can be analyzed with a Particle-Image-Velocimetry system.
Furthermore, the institute possesses a thermographic camera with a megapixel resolution. For acoustical analyses a sound level analyzer is used with a number of software modules, including frequency analysis and recording of the measured signal. For the determination of sound power output a reference sound source exists. Air quality measurements are performed with multigassensors and different sensor systems.
We are looking forward to our new experimental hall that will be finished in the fall of this year. Thus, we will be provided with different test benches which strengthen the experimental work significantly.
