Abstract:
The objective of this research is to study and predict phenomena of airflow over a building by calculating the velocity and pressure at all points of domain. The obtained data is used for the purpose of building design concerning engineering and architecture. The research is divided into two parts. The first part focuses on creating confidence in using CFD code in comparison with the pre-research, beginning with simple flow problems to the complex flow ones that are similar to the real 3-dimension building. For the case of laminar flows, the calculation agrees well with the experiments. For turbulent flows, the results from CFD code have the same trend as the measurements. In the second part of the thesis, prediction of air flow over of the JEWELRY TRADE CENTER is performed as a case study. The study is divided into two cases: single building without and with effects from the blocks nearby. Comparing with the result of a previous research in wind tunnel at the seventh level of the building reveals that results from CFD code is between the maximum and minimum values obtained from experiments; thus showing the reliability of the present numerical method.
