Dynamic simulation of Ammonia Concentration and Emission within swine barns: Part I. Model development.

摘要: A process-based model is described that simulates the dynamic ammonia concentration in room and slurry channel headspace of grower-finisher swine barns, as well emitted to surrounding environment. The Ammonia Concentration Emission Simulation (ACES) includes mechanistic sub-models describe urination frequency location, emission from individual urine puddles, slurry. Data were collected two rooms use input data for calibration validation purposes. allows hourly simulations up a 3-day period mechanically ventilated barns variety housing configurations production variables.
