Abstract |
|
|
| First: - We estimated mathematical model for hermitized model in steady-state for the dispersion of air pollutants
in low winds in three dimensions. The eddy diffusivities have been parameterized in terms of downwind distance for near
source dispersion [1]. The solution has been used to simulate the field tracer data collected at IIT Delhi in low wind
convective conditions.
Second: The analytical solution of advection-diffusion equation in unstable condition has been obtained taking power-law
profiles for the mean wind speed and vertical eddy diffusivity coefficient. The comparison between the proposed model and
data collected from nine experiments conducted at Egyptian Atomic Energy Authority has been done. The proposed model
performs well with observed concentrations. |
