REAL-TIME CALCULATION OF THE DISPERSION OF AIR-POLLUTANTS FROM INDUSTRIAL STACKS USING A PERSONAL-COMPUTER

In this paper a model sq stem is presented which enables the calculati on in real time of the dispersion of air pollutants from industrial st acks. The model is suitable for application in nonhomogeneous terrain and can run on a personal computer. It consists of two parts; a diagno stic model for the calculation of the unsteady, mass-consistent flow f ield; and a Gaussian puff model to simulate dispersion from elevated c ontinuous point sources (industrial stacks). The model system is appli ed to simulate dispersion from two industrial stacks in Thessaloniki a rea, Greece.
