RNG kε model and SST kε model

the 3D steady wind flow field around standard high building CAARC in atmospheric boundary layer was numerically simulated with software Fluent 6.3. And upon the comparison with those from wind tunnel test

it was found that numerical simulation was a feasible way to study the wind flow around high building and the distribution of wind pressure in the building’s surface. The four proposed models can reach the accuracy from the actual demand. Furthermore

it was also shown that

the numerical results were approximate to those from wind tunnel tests in the windward while between those from NPL and TJ2 tests in the side and leeward. The pressure on the windward surface was positive with the maximum at 2/3 height and the minimum on the sides and the bottom. The pressures on the leeward surface and two sides were negative. There were little differences among the results of the four models.
