Keywords: evaluation improved design CFD model wet pad cooling system laying hen house.
The simulation results for the velocity and temperature were in agreement with observed data. Heterogeneity of velocity and temperature, increasing of the humidity in high rise barn which this ventilation scheme brought were observed. Two optimization designs of ventilation and cooling system for the house were generated and simulated by CFD. When compared two upgraded cases with original house, the results showed improved case 1 was best in velocity uniformity, the temperature homogeneity in improved case 2 was outstanding, because of the younger age of air. Coupled temperature and velocity, improved case 2 is the best one, for it can provide a more comfortable microenvironment for layers. CFD simulations, when supported by experimental research, can make a great contribution to the design of ventilation system in commercial poultry houses.(Download PDF) (Export to EndNotes)
