Sapian, A R (2009) Validation of the computational fluid dynamics method for predicting wind flow around a high-rise building in an urban boundary layer condition. Journal of Construction in Developing Countries, 14(2), pp. 1-20. ISSN 1823-6499
Abstract
Virtual Experiments or, more specifically, the Computational Fluid Dynamics (CFD) method have been used in numerous airflow studies. Most CFD code providers claim that their software can simulate and model airflow around a building. However, the literature shows little or no evidence of the implementation of this software for this purpose. Therefore, this study attempts to validate and justify the reliability of this software, by investigating the wind flow around a high-rise building. The main goal of this paper is to determine if the CFD method can be used to study wind flow around a high-rise building, with a focus on the effect natural cross ventilation within a building to predict the indoor air velocity, for human thermal comfort purposes. A software called FloVent from Flomeric Inc. UK was used in the experiments. The data obtained from the simulation are compared with wind tunnel data. The result of the analysis shows that the deviation between the CFD and wind tunnel data is less than 15% on average. This result indicates that the CFD can be used as an alternative method for investigating wind flow around high-rise buildings in an urban boundary layer condition.

N.B. Descriptive scope is a count of how many of the five facets of empirical research are indicated by the words used in title, abstract and keywords. It is not intended as a judgement on the research; merely a count of the kind of word we would expect to indicate Phenomenon, Concepts, Theoretical framing, Empirical techniques, Analytical techniques. If all five are present, then a code of “5 PCTEA” will indicate this. If you feel the coding for this record is questionable, we welcome discussion around the terms we matched or the way we categorized them. The facet you would expect may not be coded, or a facet may be coded inappropriately. This can also bear on a larger question, of which facets should be treated as defining in construction management research. Please get in touch, and we will look at it. More details here
