  2. Background • Research project: “Control of Air Movement in Livestock Buildings” (1995-2001) • ... a joint research project between three Danish research groups: • The Royal Veterinary and Agricultural University, Department of Animal Science & Animal Health, Copenhagen, Denmark • Danish Institute of Agricultural Sciences, Department of Agricultural Engineering, Research Centre Bygholm, Horsens, Denmark • Aalborg University, Department of Building Technology and Structural Engineering, Aalborg, Denmark • - Livestock production an important export industry in Denmark • - Increased focus on working environment, indoor air quality, animal welfare • - New housing types and production systems • - New design tools such as Computational Fluid Dynamics (CFD) KJELD SVIDT, AALBORG UNIVERSITY

  3. Background • At the end of the project it was decided to make a one-day information seminar for professionals in the ventilation industry and consultants from the agricultural extension service. • For this seminar, a few cases reflecting research results as well as problem-cases from the industry were selected to be presented in the Virtual Reality facilities at Aalborg University. • Airflow was calculated with the commercial CFD-code Fluent version 5.5. Results were converted and displayed with the visualisation code VU (www.cerca.umontreal.ca/vu). • The results were displayed in the panorama as well as the six-sided CAVE. KJELD SVIDT, AALBORG UNIVERSITY

  4. Cases selected for VR presentation in the project • 3D airflow in a laboratory set-up with an isothermal slot inlet • Airflow and CO2-concentrations in a laboratory set-up with 4 wall inlets and “pig simulators” • Simulation of displacement ventilation in a room with closed pen partitions • Airflow in a similar room with a low momentum ceiling inlet • Airflow in a room with a radial inlet device KJELD SVIDT, AALBORG UNIVERSITY
