CFD

What?

Perform a computational fluid dynamics (CFD) simulation to analyze the flow characteristics around a 3D airfoil at varying angles of attack. The study evaluates the aerodynamic forces, lift, drag, and the impact of induced drag on performance.

How?

Modeled the 3D wing geometry in ANSYS DesignModeler
Generated a poly-hexcore mesh using the Watertight Geometry workflow.
Simulated airflow with a Mach number of 0.8395
Evaluated performance for angles of attack: 3° and 6°
Conducted postprocessing to visualize y+ distribution, Mach number, velocity components, pressure, wall shear stress, and lift-to-drag ratio.

Results

Lift coefficient (CL) increased linearly with the angle of attack from 0.2 at 3.06° to 0.4 at 6°
Drag coefficient (CD) rose significantly due to induced drag, from 0.013 to 0.04
Observed flow patterns around the wing
