Numerical investigation of headwind and crosswind conditions of Ahmed body
MetadataShow full item record
In this study, unsteady incompressible flow field 3D Ahmed body are investigated for two different slant angle. In the case of 3D unsteady flow fields, realiable k-epsilon turbulence model is used to investigate the aerodynamical effects of crosswind conditions over headwind conditions. All numerical results are compared and validated with experimental measurement and previously conducted numerical studies. The general nature of the flow field and its structure demostrated by different flow field quantities such as pressure coeeficient, streamlines, turbulence kinetic energy and velocity magnitude along various cross sections were presented for all numerical cases.
