Abstract

<p>Thermal power plant was recently built near an existing wind farm. The pollutant emitted from the thermal power plant is possibly affected by the rotating wind turbine at the wind farm, and the high concentration of the pollutant potentially reaches at the ground. However, the effect of the rotating wind turbine on the pollutant dispersion is less understood. In the present study, a large-eddy simulation was implemented to investigate the effect of the rotating wind turbine on the pollutant dispersion emitted from a point source. The arbitrary mesh interface technique was applied to represent the rotation of the wind turbine in the computational domain. The point sources were located upwind or downwind of the wind turbine. In the case of the upwind source location, the rotating wind turbine strongly affected the pollutant dispersion and increased the pollutant concentration at the ground level when the source height was equal to the wind turbine hub height. As the source height increased, the rotating wind turbine had less influence on the pollutant dispersion. In the case of the downwind sources where the velocity defect mostly vanishes, the pollutant dispersion was not strongly affected by the rotating wind turbine irrespective of the source height.</p>
