Abstract

The group analysis for the steady bidimensional turbulent diffusion equation for removal process is presented. We assume that the wind speed and eddy diffusivity coefficients depend on the height in monomial form. Some ana- lytical solutions are presented. They can be used to test numerical solutions. 1 Introduction In the last three decades, devoted attention has been attracted for a large variety of physical phenomena governed by nonlinear equations. Nonlinear diffusion mechanisms is of great interest in many physics and engineering applications, Nowadays, the influence of the vehicular traffic on the degrada- tion of urban atmosphere is focused on by researchers belonging to different fields so important for p
