A Multi-objective and CFD Based Optimization of Roof-flap Geometry and Position for Simultaneous Drag and Lift Reduction

As the transport sector is responsible for the consumption of a vast proportion of
the oil produced, it is mandatory to research feasible solutions to tackle this issue. The application of aerodynamic attachments for passive flow control and reducing resisting aerodynamic
forces such as drag and lift is one of the most practicable ways to minimize vehicle energy consumption. The flaps are one of the most innovative aerodynamic attachments that can enhance
the flow motion in the boundary layer at the trailing edge of the wings. In the present paper, the
flap is designed and modeled for controlling the airflow at the roof-end of a 2D Ahmed body
