Abstract

The steady-state distribution of particles emitted by an infinite line source in the presence of winds and atmospheric turbulence is determined by means of an electric analog approach. A logarithmic wind profile and a linear eddy-diffusivity profile are assumed, and a series of normalized curves relating the horizontal wind velocity, the vertical eddy diffusivity, and the source magnitude to the concentration in the horizontal and vertical direction are presented. A method for extending the technique to the treatment of finite line sources and point sources is indicated.
