Numerical simulations on the aerodynamics of the Ahmed body at different slant angles
In this research, the aerodynamic behavior of Ahmed’s body with slant angles of 0°, 30° and 60° is studied using ANSYS FLUENT CFD code. The flow conditions for all cases were same while the rear slant angle is varied for Ahmed’s body. The aerodynamic parameters; lift coefficient and drag coefficient were focused mainly to analyze the flow behavior, it tells the aerodynamics efficiency. The time dependent transient simulation is run to study the behavior of fluid flow. As the Reynold’s number lied 5x105in turbulent regime so to accurately capture the turbulent effects, k-epsilon two equation model with
