Abstract

Studies in many European countries have revealed that residential wood combustion is a very significant source of particle pollution. In Denmark this source contributes to more than half of the national PM2.5 particle emissions. Both air pollution from residential wood combustion and traffic are local scale problems, which for certain questions demand a detailed description of the flow around buildings. In the present work a prognostic flow model was applied in order to improve the understanding of the dispersion conditions governing the highest pollutant loads, and to produce recommendations regarding the optimal position and height of the stack depending on the type of roof. Specifically, this paper presents CFD simulations with MISKAM of pollutant dispersion from a domestic stack over an isolated building with flat or pitched roof. A number of basic cases have been studied that demonstrate the influence of the relative stack height and the slope of the roof on plume dispersion. To our knowledge, it is the first time that MISKAM is being engaged on the simulation of that type of configurations. The results are compared against a wind tunnel study, conducted to investigate the dispersion of smoke released from domestic stacks. Previous studies have documented that MISKAM can be considered as one of the well established CFD tools for atmospheric dispersion studies in built-up areas. However, this study also has revealed a need for further studies of some of the assumptions and algorithms in MISKAM. The above statement is demonstrated with specific examples.
