Effects of Varying Wind Angles and Increasing Concentration on Air Pollutant Dispersion from Cooling Towers to Urban Area using Computational Fluid Dynamics Software

Managing and improving the air quality across urban areas can be achieved by studying transport behaviour of pollutants. In this work, effects varying wind angles increasing concentration on pollutant dispersion from cooling towers to area were investigated using computational fluid dynamics (CFD) software; OpenFOAM modified k-ω SST turbulence closure acquire steady-state flow field based Reynolds Averaged Navier-Stokes Equation (RANS) approach. The results showed that direction for velocity profile (1 0 0) (Cos30 Sin30) (Cos45 Sin45) affected pollution with worst scenario being 0). addition, reducing diffusivity constant (Dt), thus concentration, 0.02 0.001 increased considerably. This research shows benefit applying CFD approach toward managing challenges dispersion.
