“…Some studies have used database-assisted or testing-assisted design methodologies [2][3][4], while wind loading simulations performed via stochastic processes have drawn significant interest over the past few decades [5][6][7][8]. Wind loads are critical for tall buildings [9], but also for low-rise structures [10][11][12] similar to this study.…”

“…Zhao Liu et al [6] performed a twisted wind flow on a square mega tall building using wind tunnel test and the results of pressure distribution are studied. In order to reduce the wind load on structure, many major and minor modifications are made on buildings with different shapes and is performed by the researcher Ashutosh Sharma et al and Kim Y., Kanda J [7,8]. Further, the researchers continued with the detailed review of shape modifications in buildings such as curve corners and major modifications such as altering the building shape and elevation.…”

In recent years, the construction of skyscrapers is emerging in many countries and the study on the behavior of wind around the building receives an additional interest among structural engineers and architects. Mostly, tall skyscrapers are planned in the shape of 'Y' in order to have a maximum exterior view and to support the central core of the structure. In the current scenario, it is important to study the actual wind load for irregular plan shape building. This paper presents the numerical wind flow simulation around 'Y' plan shape tall building using ANSYS Fluent software and validation is done using wind tunnel testing. The building model and wind velocity are scaled to the ratio 1:300 and 1:5 respectively. A wind velocity of 10 m/s is applied both for wind tunnel testing and for the numerical simulation. Error analysis is carried out in order to check the accuracy of the results obtained between wind tunnel and CFD. From the test results the mean C p is investigated for various faces of the building for the wind angle 0˚, 45˚ and 90˚ from both using CFD and wind tunnel. The investigation of drag and lift coefficient is made on Y-plan shape building and it is observed that the maximum drag occurs at 45˚ wind angle, because of the less projected area when compared with the other wind angles 0˚ and 90˚ respectively. Further, this paper continues with the physics of wind flow behavior around Y-plan shape building and flow character such as vortex formation, streamlines and identification of wake region for different wind angles.

“…Besides these studies, most of the researchers have focused on the measurement of peak pressure for cladding design and induced forces. Further, to mitigate the wind-induced loading on buildings, the effectiveness of several architectural features of the building has been reviewed by Sharma et al (2018). Moreover, in addition to wind-induced loading, the surrounding wind environment is also a concern, as it affects natural ventilation, pollutant dispersion, building energy demand, and pedestrian comfort.…”

The presence of buildings that surround the wind environment adversely affects at the pedestrian level. The present study investigates the effect of different arrangement of two buildings on wind flow structure and modification of wind speed conditions at the pedestrian level. The investigation was carried out for parallel, tandem, and staggered arrangement of two buildings using computational fluid dynamics simulations. The wind tunnel experiments were conducted to validate the computational fluid dynamics results. The computational fluid dynamics simulations were performed using the standard [Formula: see text] model with LK modification and revised closure coefficients. Different flow features such as skew-symmetric vortex structure for parallel arrangement, reattachment of shear layer on the surfaces of the downstream building for tandem arrangement, and deviation of wake region behind the upstream building to leftward of the flow direction for staggered arrangement were observed. It was observed that the strong wind conditions were mostly affected by tandem and parallel location of the twin buildings. The results of numerical simulation obtained using the modified SKE model were found to be in good agreement with the experimental results.
