- Abstract
- A pollutant-laden transport in fully developed turbulent boundary-layer flow has been investigated using the k-omega turbulence model. The scalar transport equation of the pollutants concentration, which is based on the continuous-phase approach, is adopted. The pollutant settling process is taken into account with a modified settling velocity appearing in the pollutant concentration equation. A new eddy viscosity model is proposed in the turbulence modelled equations to couple the velocity field and the concentration field. The numerical results are compared with the experimental data, and good general agreement is achieved.
