An analytical model for the transport, dispersion and elimination of air pollutants emitted from a point source

摘要: Abstract The solution of the complete transport diffusion equation with a first order reaction term is obtained for continuous source. A deposition velocity boundary condition met at ground and, optionally, similar leakage can be base superjacent layer. identification preliminary transformation dependent variable that eliminates and sink terms permits particularly simple analytic solutions to by means conventional Laplace transform, Green's function methods. Prior are compared these results. linearisation without an overlying layer provides extension Gaussian plume result account taken pollutant settling velocity, absorption reaction. accuracy this assessed.
