Abstract / Zusammenfassung

As a new type of pig housing system, naturally ventilated pig buildings with outdoor exercise yards (NVPBOYs) have better animal well-being and thus are receiving increasing interest. However, there is lack of information on the transport and dispersion characteristics of air pollutants for this type of pig
house. Therefore, the aim of this study was to investigate the dispersion of air pollutants from a NVPBOY. Experiments with a scaled NVPBOY model were carried out in a large boundary layer wind tunnel. Air velocities and concentrations of a tracer gas were measured at a vertical plane downwind
the scaled model using a Laser Doppler Anemometer and a fast Flame lonisation Detector. A tracer gas concentration accumulation area was observed in the wake of the scaled model at the height where air vortex and peak turbulent kinetic energy occurred. The results contribute to a better understanding
of air pollutants dispersion characteristics in relation to airflows.
