Abstract

The paper analyzed the wind-induced pollutant dispersion in a built environment using computational fluid dynamics simulation.  SF6 was used as the tracer gas released from a roof stack. The steady-state analysis used to develop the adaptive mesh was carried out using the RNG-KE turbulence model. The computational domain and boundary condition for the wind flow on the urban area was adopted as recommended by the Cost guideline. Also, the SF6 species was modeled as a passive scalar transport convection-diffusion equation. From the result, it was observed that the funnel effect and vortex shedding effect reduces the concentration level of pollutants within a locality.
