A Comparison of Advection Diffusion Equation Solutions, Observed Data, and Statistical Results
In this paper, the statistical procedure is compared to the analytical solutions of an advection-diffusion equation describing air pollution spread in a limited atmospheric boundary layer from a continuous point source. The equation is formulated by assuming the eddy diffusivity and wind velocity as the constant and the power law of vertical height. It has been observed that the expected concentration for eddy diffusivity and wind velocity as constants has a worse agreement with the actual concentration than the expected concentration for wind speed and eddy diffusivity as variables.
