The nonlinear dynamics of a transverse galloping blunt body oscillator is analyzed with respect to its geometric shape and size. The oscillator's equation of motion is studied using an approximation f...
This is the first of three lectures prepared by the authors for the von Karman Institute that deal with the subject of aerodynamic shape optimization. In this lecture we introduce some theoretic...
Deterministic engineering design often leads to unexpected or physically unrealizable results. This is due to the fact that deterministic design is not able to capture the effects of even slight natur...
In this paper we examine the low Reynolds number flow past a harmonically plunging,pitching, and deforming airfoil, both individually and in combination. The lift and thrust characteristics of t...
A model problem, based on the NACA0012 airfoil, is studied. The thickness distribution of the symmetric NACA0012 airfoil is optimally approximated with a 4th-order Bezier curve. This best-fit ap...
This paper addresses the aerodynamic performance of Busemann-type supersonic biplanes at both design and off design conditions. An adjoint-based optimization technique is used to optimize the aerodyna...
INCE the adjoint method was introduced to aerodynamic shape optimization in 1980s [1,2], this method has become a popular choice for design problems involving fluid flow and has been succe...
This paper is an addendum to a recent publication on a Comparative Study of 3D Wing Drag Minimization by Different Optimization Techniques; with a focus on a path forward towards the development of a ...
The main goal of this paper is to document a comparative study of different CFD based optimization techniques applied to the so lution of a 3D wing drag minimization problem.
We present a design optimization method for reducing the wave resistance (drag) of surface piercing hulls.
This paper presents a numerical method for aerodynamic shape optimization problems in compressible viscous flow. It is based on simultaneous pseudo-time stepping in which stationary states are o...
This paper focuses on wing optimization via control theory using a multi-point design method. Based on the design methodology previously developed for wing section and planform optimization at a speci...
This is the second of two lectures prepared by the authors for the von Karman Institute that deal with the subject of aerodynamic shape optimization.
This is the first of two lectures prepared by the authors for the von Karman Institute that deal with the subject of aerodynamic shape optimization.
In this paper, an Adjoint-based automatic design methodology has been applied to redesign the wing of the P51 \Dago Red", an aircraft competing in the Reno Air Races.
