Suppression of airborne pollutant infiltration into the occupation region by the air curtain was numerically studied in the present work. The computational analysis was depending on the two-dimensional conservation equations of mass, momentum and species concentration for the incompressible isothermal turbulent flow with a standard k-Εtwo-equation turbulent model adopted for turbulence closure. Time averaged turbulent stream-functions and species-functions were respectively defined to vividly visualize the fluid flow and pollutant dispersion. The effects of ejection velocity, air curta...
