An Approach to Practical Aerodynamic Calculations.
Abstract
The emphasis of these lectures is on the numerical solution of three dimensional boundary layer equations using forms of Keller's Box scheme and interaction with solutions of inviscid Flow equations. Calculations are described for the flow over a circular cylinder started impulsively from rest and a prolate spheriod at angle of attack and were obtained with prescribed free stream velocity distribution; the results emphasize the need for the Characteristic Box finite difference scheme, which automatically satisfies the numerical stability criterion, in regions of flow where the w-velocity component is negative. Corresponding calculations, this time with a novel ellipse, over an oscillating airfoil and around wings; the results confirm that the interactive procedure provides accurate solutions, without numerical problems, in regions of flow separation.
