Numerical Simulation of Solid Particle Dispersion in the Air of Vilnius City
Journal Title: Journal of Environmental Engineering and Landscape Management - Year 2008, Vol 16, Issue 1
Abstract
One of the main methods for the air quality assessment and forecast is numerical simulation of pollutants. In order to simulate the dispersion of solid particles (SP) in the air, there may be applied the package of “Phoenics” software in which the proximity methods of equation solution are used, because an accurate analytic solution of movement equations is not possible to be applied. The software was used in Žvėrynas districr of Vilnius city in which the exact values of SP were selected. The paper presents the technique of mathematical simulation of SP dispersion in the air, the Algebraic Slip Model is described which is used for the solution of the problem; the model uses calculation-based formulas. Based on the results of the experiment (the values of SP concentration) and the obtained results by applying “Phoenics” mathematical simulation program, the feasibility of the simulation program for modeling the SP concentration dispersion is determined. The results of simulation are submitted in figures and tables, and conclusions have been derived.
