[Abstract] The study of airflow and contaminant transport in airliner cabins is very important for creating a comfortable and healthy environment. To know how the air and contaminants are distributed and transported in the whole air cabins fast, In this study, a zonal model called COwZ is chosen. This study validates the COwZ model using data from a mockup cabin in the literature, The numerical results are compared to the experiment data. The air distribution could reflect the flow trend approximately . Most of the measure points whose non-dimensional (SF6)concentration profiles are with an error less than 25%. The results indicate that COwZ model is practicable for simulating airlinecabin environment .
