Airfoil
My airfoil is a circle of radius 1.5 cm, with a 15 cm long tail from the center of the circle. The bottom side of the foil is a tangent arc from the end of the tail to the circle, and the top of my foil is a tangent line from the end of the tail to the circle.
Our task was to simulate air flowing across said foil, and finding the lift due to viscous force and pressure force.
Pictured is the .dxf file of my airfoil design. I created the initial drawing in SolidWorks, then imported it, generated a mesh, and set up the physical parameters for simulation. With everything in place, I ran the simulation to analyze the airfoil's performance.
Pictured are the plots for the pressure difference in the airfoil, the key to gaining lift, and the velocity field around the airfoil to further demonstrate how the airfoil acts with fluids.
This simulation was great practice for using COMSOL to simulate fluid flow and understanding the significance of airfoils in engineering.
