Mathematical Solution of Two Dimensional Advection-Diffusion Equations

The Laplace conversion technique was applied to the Advection-Diffusion Equations (ADE) in two dimensions to obtain crosswind integrated normalized concentration, consider wind speed and the vertical eddy diffusivity 'Kz' are constant. Data set used from atmospheric diffusion experiments conducted in the northern part of Copenhagen, Denmark was observed for hexafluoride traceability (SF6). A comparison was made between current results, previous work results and data. One finds that the present and previous work crosswind integrated normalized concentration results are agreement well with observed data (one to one) and others lie inside the factor of two and four
