Abstract

In modem livestock buildings the design of the ventilation systems is important in order to obtain good air distribution. The use of Computational Fluid Dynamics for predicting the air flow and air quality makes it possible to include the effect of room geometry, equipment and occupants in the design of ventilation systems. However, it is not appropriate to include the detailed geometry of a large group of lying or standing animals affecting the air flow in the building.
It is necessary to have relatively simple models of the animals, which are easier to implement in the computer models. In this study laboratory measurements in a ventilated test room with "pig simulators" are compared with CFD-simulations.
