Calculating the Coefficient of Lift and Drag at various angles of attack in ANSYS
I want to plot a graph of Coefficient of Drag for a 3D airfoil at various Angles of Attack.
I have done a simulation in ANSYS FLUENT with the Angle of Attack as the INPUT PARAMETER and the Drag force as the OUTPUT PARAMETER.
I should be using the formula shown below within the PARAMETER SET....
MY QUESTION is this, what should I include as my reference area (S)? And how do you calculate it for various AoA?
