Abstract

A one-dimensional model based on k-e taking into account the change in basic atmospheric flow with height and stability J. Servert*, J. Lumbreras^, M.E. Rodriguez^ & A. Crespc/ ^Department of Energy and Fluid Mechanics, Universidad Politecnica de Department of Chemical and Environmental Engineering, UPM, Spain Abstract A one-dimensional model has been developed to evaluate the ambient air quality standards due to the discharge of pollutants through a stack. This model has been applied to a tire thermolysis plant in Ardoncino, Leon, Spain. The plume centerline is evaluated by mean of the fluid mechanics conservation equations and a gaussian-distribution hypothesis is made to estimate the flow magnitudes in radial direction. The mass entrained in the plume is calculated with two different models, one based on the difference of velocities (Escudier [8]) and the other on the turbulent viscosity (Tamanini [19]). The model takes into account the following effects: ambient turbulence, tu
