THREE-DIMENSIONAL, ANALYTIC SOLUTIONS TO THE PROBLEMS OF DIFFUSION OF WIND-DRIVEN CONTAMINATION

Abstract

Estimates of critical distances, up to which dust, aerosols, and (toxic) fumes may be driven, under the influence of various wind and diffusivity conditions, require that three-dimensional solutions to the problem of wind- driven contamination be derived, for application to range safety problems. The following work was directed to this end: (1) analytic solutions for constant wind and constant diffusivity were derived; (2) three -dimensional analytic solutions were derived, under the assumption that wind speed and eddy diffusivity vary, either in accordance with the conjugate power laws, or in a more general fashion; (3) a new method of solution is suggested which may be used for solving diffusion problems of a more general nature; (4) five particular, three-dimensional parabolic source solutions were derived.
