On the Wake and Drag of Bluff Bodies [PDF]
Journal of the Aeronautical Sciences, 1955 A modification to Kirchhoff's free streamline introduces the parameter k = √(1- C_ps), which allows arbitrary base pressure and which must depend on the dynamics of the wake. For a cylinder of given cross-sectional shape, the drag, C_D, and the wake width, d', are functions of k only.
