The investigations were carried out making use of experimental identification of the flow. Concise information is presented concerning the CFO method applied in the modeling of the airflow and gaseous contaminant. The tested object has been characterized, as well as its respective experimental data. The ways of generating its simulation model has been described, paying special attention to the simulation of the diffuser. TI1e results of prediction have been compared with the results of measurements of the air velocity and the concentration of gaseous contaminant. Attempts have been made to improve the quality of the obtained results of prediction of the distribution of tracer gas concentration by increasing the accuracy simulating the diffuser, the jct leaving the diffuser and the airflow pattern in surrounding the contarninant source and suction nozzle. It has also been tried to utilize the results of numerical prediction for the purpose of determining the effectiveness of the local exhaust.}, type={Article}, title={Numerical Prediction of the Propagation of Gaseous Contaminants in the Ventilated Laboratory}, URL={http://ochroma.man.poznan.pl/Content/123381/PDF/3_AE_VOL_32_3_2006_Lipska_Numerical.pdf}, keywords={ventilation, laboratory, airflow, contamination, numerical prediction}, }
