Description: The design of livestock building ventilation systems is based on the premise of complete mixing. The complete mixing assumption involves equating the thermodynamic properties of the exhaust air to the average thermodynamic properties of the bulk airspace so as to enable the calculation of steady-state heat and moisture balances. A research project was initiated at the University of Guelph to assess the validity of the complete mixing assumption for slot-ventilated livestock buildings. The emphasis in this report is on the identification of physical phenomena which could create a departure from complete mixing and on experimental techniques to quantify incomplete mixing. A summary is given of evidence to support the occurrence of incomplete mixing and the con sequences of incomplete mixing are discussed. The interested reader is referred to Barber (1981) for a more complete derivation and discussion of the concepts introduced in this paper.
