Prediction of personal exposure to contaminant sources in industrial buildings using a sub-zonal model

Numerical simulations made within a large, empty ventilated room using COwZ have been compared with published experimental measurements and results from CFD modelling studies. Comparisons have also been made with the results of CFD studies made when the room was occupied. The simulations show that the local impact of a person is significant in some cases and should be considered for the assessment of personal exposure.
