cord-348063-5yd7hr5e	Li, Fei	Predicting contaminant dispersion using modified turbulent Schmidt numbers from different vortex structures	2018-02-15		.txt	text/plain	5416	343	56	In this study, turbulent Schmidt number (Sc(t)) was modified as a function of turbulent kinematic viscosity rather than a constant value to better simulate dispersion of airborne contaminant in two typical enclosed spaces: an aircraft cabin and an office room. Fig. 2 shows comparison of experimental data from particle image velocimetry (PIV) measurement [29] with simulated airflow patterns in CS4 of the aircraft cabin ( Fig. 1 (a) ) by three turbulence models. Fig. 3 shows comparison of predicted airflow velocities with experimental data [22] at poles V1 to V3 for the office room ( Fig. 1 (b) ) by different turbulence models. In this paper, a method to modify Sc t as a function of turbulent kinematic viscosity based on airflow vortex structures was introduced to better simulate dispersion of airborne contaminant in two typical enclosed spaces: an aircraft cabin and an office room.	./cache/cord-348063-5yd7hr5e.txt	./txt/cord-348063-5yd7hr5e.txt
