Abstract

In this work, the standard version of the k - e turbulence model is extended to take into account stratification effects in the atmosphere. Empirical constants of the k - e model have been modified by the aid of the similarity theory of Monin and Obukhov for the atmospheric surface layer. A finite element model using penalty formulation for incompressible turbulent flow is applied to solve a flow above a flat plate heated from above. 1. Introduction. The concentration of a passive pollutant depends on the flow around spreading source. So the determination of the concentration requir
