If these small structures are not designed for a dynamic load or the corrected amplified load, it will collapse. This study aims to investigate the effect of street canyon width towards wind flow by observing a simplified model of 4 symmetrical high-rise buildings with changing street canyon width. The numerical model uses CFD with RANS in OpenFOAM v1912 which is validated with experimental results using a low wind speed wind tunnel and Particle Image Velocimetry (PIV). An Experiment has been performed in BBTA3 using a model with 1:420 scale, there are 2 models with different street canyon width. The result showed there is an increment of the mean wind speed about 5.92-20.20%.[/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Author keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Indexed keywords” size=”size-sm” text_align=”text-left”][vc_column_text][/vc_column_text][vc_empty_space][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][vc_empty_space][megatron_heading title=”Funding details” size=”size-sm” text_align=”text-left”][vc_column_text]This research is done by the help of the Program Penelitian, Pengabdian kepada Masyarakat dan Inovasi ITB (P3MI-ITB) Grant scheme 2017-2019 from ITB.
