Scale model experiments to determine the effects of internal airflow and floor design on gaseous emissions from animal houses

Ammonia and greenhouse gas emissions from fattening pig house with two types of partial pit ventilation systems

“…Meanwhile, the dispersion and deposition of gaseous contaminants are mostly affected by airflow inside the livestock building (Zhang and Strom, 1999;Morsing et al, 2008).…”

Numerical modelling of airflow and gas dispersion in the pit headspace via slatted floor: Comparison of two modelling approaches

“…In a livestock building with a slatted floor system, pollutants like ammonia and odours are mostly emitted from the zone near the slatted floor, either the floor surface or the slurry pit under the floor (Zong et al, 2014a, b). Airflow patterns in the pit headspace and air exchange between pit and room space can significantly affect the ammonia dispersion which will further affect indoor air quality and emissions from the building (Morsing et al, 2008). Therefore, a better understanding of the airflow characteristics and mass transportation mechanisms in the pit headspace is highly desired.…”

Particle image velocimetry measurement of indoor airflow field: A review of the technologies and applications

“…Airflow field measurement can provide reliable quantitative information of indoor air distribution or local air velocity around occupant [6][7][8]. However, experimental measurement is usually difficult and time-consuming.…”
