This video shows how to compare any two airfoils using XFLR5. Here airfoils NACA 4412 and NACA 2212 is used for comparison and appropriate airfoil can be selected using data collected from the graph shown in the video later. In XFLR5 we can analyse the performance of airfoils in different conditions, for example we can change the Reynolds number, change speed of the plane to understand how different airfoil performs in different conditions.
