Comparative analysis of numerical and experimental studies of the airflow around the sample of urban development

Abstract

Abstract In this paper, on the background of a short overview of the recent advances in the field of Environmental Wind Engineering (EWE), a comparison of wind tunnel experiment and numerical simulation for some cases of airflow around an urban layout have been reported. The purpose of the study is quantitative and qualitative comparison of measurements in the wind tunnel as well as numerical simulation using Ansys Fluent software. The study is concerned mostly with the analysis of parameters which are essential in the building industry, such as pressure and velocity fields. In the numerical analysis the k-ε realizable model of turbulence with the basic model of boundary layer – Standard Wall Treatment, were used. Particular attention has been paid to accurate depiction of the conditions on the inlet and the selection of suitable computing.
