A vortex in cell (VIC) method combined with an immersed boundary (IB) method is applied to the simulation. The Reynolds number Re, based on the diameter D of cylinder and the flow velocity upstream of the front cylinder, ranges from 200 to 9500. The distance L between the cylinders is varied from 1.5D to 8D. The simulated flow characteristics, such as the behavior of the shear layers separated from the cylinders, the vortex shedding and the fluid forces acting on the cylinders, are favorably compared with the existing results. The simulation can also successfully analyze the effects of Re and L on the flow characteristics. These simulation results demonstrate that the VIC method combined with the IB method is usefully applicable to the simulation of incompressible flows around two tandem cylinders.[/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]Immersed boundary method,Two tandem cylinders,Vortex in cell method,Vortex shedding,Wake[/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]The investigation presented in this paper was supported by the MEXT Program funded by the Ministry of Education, Culture, Sports, Science, and Technology in Japan.[/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=”DOI” size=”size-sm” text_align=”text-left”][vc_column_text]https://doi.org/10.17654/FM019040787[/vc_column_text][/vc_column_inner][vc_column_inner width=”1/4″][vc_column_text]Widget Plumx[/vc_column_text][/vc_column_inner][/vc_row_inner][/vc_column][/vc_row][vc_row][vc_column][vc_separator css=”.vc_custom_1624528584150{padding-top: 25px !important;padding-bottom: 25px !important;}”][/vc_column][/vc_row]
