Application of Computational Fluid Dynamics Model in High-Rise Building Wind Analysis-A Case Study

Abstract

Over the years, wind loading codes has been a crucial tool in determining design wind loads on buildings. Due to the limitations of these codes especially in height, wind tunnel testing is recommended as the best approach in predicting wind flow around buildings but carrying out wind tunnel testing in the preliminary as well as final design stage of a project has proven uneconomical and incurs additional cost to the client. In response to this, CFD which is a virtual form of wind tunnel testing was developed. From immersive researches and experiments carried out by previous researchers, best practice guidelines have been given on the use of CFD in predicting wind flow around buildings. This paper compares the results of a case study application of computational fluid dynamics simulation in determining the wind loads on the facade of a typical 48.8m high-rise building to the predictions given in British wind Standards BS6399-2:1997, using (BS6399-2:1997).

CFD Analysis of Fluid-Dynamic and Heat Transfer Effects Generated by a Fixed Electricity Transmission Line Interacting with an External Wind

“…Resonance occurs when the emission frequency is close to the natural frequency of the structure. It means that it is the vibration caused by eddy current [13,14]. The breeze vibration of transmission lines is basically caused by eddy current.…”

The Evolution and Advancements in the field of Wind Engineering: A State of Art Review

“…CFD proves to be a powerful alternative capable of analyzing the flow separation and visualization accurately. A case study to check the feasibility of using CFD model in high-rise building wind analysis was carried out [31]. The researcher stated that strict adherence of CFD for wind around buildings can definitely serve as an alternative to time consuming wind tunnel test.…”
