Optimization of the Ventilation System for a Forced Ventilation Piggery

open access: yesJournal of Green Building, 2009
Abstract Pigs are subjected to intensive environment control and management in order to achieve higher productivity. This is due to their sensitivity to climatic variation, which strongly affects their growth. This paper reports the design optimization of a forced ventilation piggery using computational fluid dynamics.
