Prediction of Air Flow Pattern Influenced by Incoming Jet Direction with FEM in Confinement Livestock House

Atsuo IKEGUCHI

ABSTRACT

    Prediction of air flow pattern affected by incoming jet directions was performed in a confinement livestock house by using FEM assuming a two dimensional, steady state, isothermal, incompressible and viscous air flow. Zero equation model was applied as a turbulent model. The numerical analysis used in the study assumed the use of a microcomputer, and the results obtained from the numerical analysis were examined by comparing with those of the model experiment. The findings indicate that even if pens and sows existed as obstructions in ventilated space, and even when incoming jet direction differed, a rough agreement between FEM and model experiment was observed for qualitative air flow pattern. With regard to air velocity, such agreement was not obtained.
