Abstract

In this paper, in order to achieve a suitable accuracy and high-speed method for simulating three-dimensional emission propagation in a room due to a gaseous pollution source, a Pressure Version of the Zonal Method has been developed and two pollution problems have been investigated. At the first problem, for validating the results of this research, the emission simulation through contaminated air into a room with dimension of 3×4×2. 5 m via an air-conditioning gate mounted on the wall near the ceiling is done and the results have been compared with those of the numerical solution of Navier-Stocks Equations and the experimental data. According to this comparison, the percentages of average error between the present results and the experimental data, and also between the present results and those of the numerical solution are 26. 8 and 10, respectively. After that, considering both constant and instantaneous gaseous pollution sources in a room with dimensions of 3×4×3 m, pollution distributions in the room have been evaluated. According to the results of this research, this Zonal Method can obtain acceptable results in far less time than those of the experimental and computational fluid dynamics methods. Therefore, this method can be efficient for considering time-consuming environmental problems.
