| Abstract: | The impact of the single building height, the elevation or distance between tWO parallel build- ings on the wind field around two parallel buildings was studied. The standard model was applied in the calculation. The wind fields around buildings were simulated under various layouts. Characteristics of 3D field were discussed and compared with each other. The results show that the factors like the single building height and the elevation between two parallel buildings, the single building height and the dis- tance between two parallel buildings have a synergistic effect on the wind filed. |
