Comparison of various k-ε models and DSM applied to flow around a high-rise building - Report on AIJ cooperative project for CFD prediction of wind environment

Abstract: Recently, the prediction of wind environment around a building using Computational FluidrnDynamics (CFD) technique comes to be carried out at the practical design stage. However, there havernbeen very few studies which examined the accuracy of CFD prediction of flow around a high-risernbuilding including the velocity distribution at pedestrian level. The working group for CFD prediction ofrnwind environment around building, which consists of researchers from several universities and privaterncompanies, was organized in the Architectural Institute of Japan (AIJ) considering such a background. Atrnthe first stage of the project, the working group planned to carry out the cross comparison of CFD resultsrnof flow around a high rise building by various numerical methods, in order to clarify the major factorsrnwhich affect prediction accuracy. This paper presents the results of this comparison.

Cross Comparisons of CFD Results of Wind Environment at Pedestrian Level around a High-rise Building and within a Building Complex

Abstract: Recently, prediction of the wind environment around a high-rise building using Computational Fluid Dynamics (CFD) has been carried out at the practical design stage. However, very few studies have examined the accuracy of CFD including the velocity distribution at pedestrian level. Thus, a working group for CFD prediction of the wind environment around a building was organized by the Architectural Institute of Japan (AIJ). This group consisted of researchers from several universities and private companies. In the first stage of the project, the working group planned to carry out cross comparison of CFD results of flow around a single high-rise building model placed within the surface boundary layer and flow within a building complex in an actual urban area obtained from various numerical methods. This was done in order to clarify the major factors affecting prediction accuracy. This paper presents the results of this comparison.

The COST 732 Best Practice Guideline for CFD simulation of flows in the urban environment: a summary

Abstract: This paper is a summary of the "Best Practice Guideline" (BPG) document (Franke et al., 2007) produced in the framework of the European COST Action 732 "Quality assurance and improvement of micro-scale meteorological models", available from the site given in the reference section. The full document provides guidelines for undertaking simulations that are used to evaluate micro-scale obstacle-accommodating meteorological models. This paper provides an overview of the topics covered in the full document without reproducing the specific recommendations.
