Equipment of the Air Physics Laboratory

High precision air velocity sensors

A 2-D LDA. Apart from that the lab has one 1-D LDA, a TSI multi-function air velocity and air quality instrument, as well as a testo multi-function air velocity and air quality instrument.
A multi-channel air velocity measurement unit with up to 20 measurement channels.
Two high precision research ultrasonic air velocity sensors with measurement frequency of 50 Hz.
A multi-channel 3-D ultrasonic air velocity measurement system with up 8 channels.

Air quality instruments

Three INNOVA multi-gas monitors with multiplex that can sample concentration data up to 12 positions and a TSI Dust counter (old model).

Wind tunnels

Wind tunnels in different scales (mass transfer and emission in boundary layers; CFD validation data generation etc.).

Wind tunnel 1,5 m x 1,5 m in cross section.
Wind tunnel 50 x 50 cm in cross section.
1:10 scale emission building model.
1:6 scale emission building model.
Effects of ventilation rates on NH3 and odour emissions with scale model and pig slurry.
Two-dimensional ventilation chamber represented a building pig section with slatted floor

Other models

Artificial pigs with controlled heat production give an impression of air movements.
