Review of Wind Tunnel Modelling of Flow and Pollutant Dispersion within and from Naturally Ventilated Livestock Buildings

Ammonia emissions from naturally ventilated livestock buildings (NVLBs) pose a serious environmental problem. However, the mechanisms that control these are still not fully understood. One promising method for understanding is physical modelling in wind tunnels. This paper reviews studies have used this to investigate flow or pollutant dispersion within NVLBs. The review indicates importance of tunnels and processes most investigated flow, while only few focused on dispersion. Furthermore, simulated all essential parameters approaching boundary layer. Therefore, discusses shortcomings provides tips recommendations further research respect.
