Analysis of aerodynamics around tall buildings with several configurations

The streamlined exterior shapes of tall buildings are important to reduce the effect wind. Therefore, an examination different techniques for design is required. This study aims analyses some select most in order high wind risks. benchmark used current a building with height 120 m and triangular cross-section side length 20 m. A square twisted as modified model about rotation angle 45° each path. Six configurations this type tested radiuses fillet on their edges, which 0, 1, 2, 3, 4, 5 respectively. All geometries created by SolidWorks, while mesh simulations achieved using ANSYS Fluent. Great agreement obtained between results previous related benchmark. Using can lead reduction drag coefficient 27.5% relative Wind horizontal direction be reduced geometry. But terms separation, large radius avoid early separation air.&nbsp
