This study represents a comprehensive investigation of the aerodynamic characteristics of two
interfering tall buildings. The influence of key parameters, such as the aspect ratio (Hi/B = 3, 4, 5, 6, 7.5,
8 & 10), gap ratio (HL/B = 1 & 2), and height ratio (H1/H2 = 2, 1.33, 1.0, 0.75 & 0.5) is discussed. The
study is based on turbulent modeling for steady, incompressible flow field. Dimensional
... [Show full abstract] analysis was
adopted to find the non-dimensional groups affecting the wind loading on the front building. Error
analysis was carried out to determine the best correlation relating the key parameters and the wind
loading. Optimization was used to minimize the wind loading on the front building. Interesting findings
and suggestions are reported.
