Methodology for calculating aerodynamic sensitivity derivatives

AIAA Journal, 1992
Summary: A general procedure is developed for calculating aerodynamic sensitivity coefficients using the full equations of inviscid fluid flow, where the focus of the work is the treatment of geometric shape design variables. Using an upwind cell-centered finite volume approximation to represent the Euler equations, sensitivity derivatives are ...

Calculation Methods for Aerodynamic Flows—a Review

1986
The present volume has been arranged so as to emphasize present abilities to calculate flows involving three independent variables and, at the same time to provide a background of the two-dimensional approaches upon which they are based. In the earlier review by Cebeci, Stewartson, and Whitelaw [1], two-dimensional flows were considered in some detail,

Progress in high-lift aerodynamic calculations

31st Aerospace Sciences Meeting, 1993
The current work presents progress in the effort to numerically simulate the flow over high-lift aerodynamic components, namely, multi-element airfoils and wings in either a take-off or a landing configuration. The computational approach utilizes an incompressible flow solver and an overlaid chimera grid approach.
