SIMULATION OF WIND FLOW AROUND A GROUP OF SQUARE CYLINDERS WITH VARIABLE TRANSVERSE SPACING BY k-ε TURBULENCE MODEL
Keywords:
Group of square cylinders, k-ε turbulence modellingAbstract
The effect of wind loading on buildings and structures has always been a major area of interest forstructural engineers and architects. In most cases, the numerical simulations of wind flow are notavailable with the computational fluid dynamics. In the present paper, the theoretical investigationsof wind effect as well as wind flow pattern on staggered square cylinders are studied. Wind flowaround a group of square cylinders is simulated by a k-ε turbulence model (Mondal and Bhattacharia,2005) in finite volume method and the relevant flow patterns of wind have been investigated. Thecalculated results are compared with the experimental results on square cylinders conducted byMandal and Islam (1980 - 1981) and very good agreements are found.
