Panel Method Spreadsheet (Updated 6/15/2018)

 

This workbook implements the vortex panel method for a 2D airfoil.   The algorithm is from Kuethe and Chow, Foundations of Aerodynamics, 4th Edition, Wiley (1986).   Detailed implementation instructions are provided in a separate pdf file.  Inputs are coordinate data for the airfoil (from a source such as Abbott and von Doenhoff, Theory of Wing Sections, Dover (1959) and the angle of attack.   This being an inviscid flow calculation, the flow will remain attached for any angle of attack.    The calculation returns the pressure coefficient Cp as a function of position and a streamline plot.  The student can use these local results to compute the section lift coefficient, etc.
