Efficient Aerodynamic Shape Optimization in MDO Context [PDF]
PAMM, 2005 AbstractThe aerospace industry is increasingly relying on advanced numerical flow simulation tools in the early aircraft design phase. Today's flow solvers, which are based on the solution of the compressible Euler and Navier‐Stokes equations, are able to predict aerodynamic behaviour of aircraft components under different flow conditions quite well [1]

Efficient Aerodynamic Shape Optimization [PDF]
10th AIAA/ISSMO Multidisciplinary Analysis and Optimization Conference, 2004 Since the present author first became involved in computational fluid dynamics, around 1970, the landscape has changed dramatically. At that time, panel methods had just come into use, and the world’s fastest super computer, the Control data 6600, had only 131000 words of memory (about 1 megabyte).

Parameterization adaption for 3D shape optimization in aerodynamics [PDF]
, 2014 When solving a PDE problem numerically, a certain mesh-refinement process is always implicit, and very classically, mesh adaptivity is a very effective means to accelerate grid convergence.

Simultaneous pseudo‐time stepping for aerodynamic shape optimization [PDF]
PAMM, 2005 AbstractIn this paper we discuss about numerical methods for aerodynamic shape optimization problems. These problems require efficient CFD techniques to solve the state (as well as costate) equations and fast algorithms for solving the optimization problems. Both of these are independent active areas of research since long time.

Aerodynamic shape optimization of a low drag fairing for small livestock trailers [PDF]
, 2008 Small livestock trailers are commonly used to transport animals from farms to market within the United Kingdom. Due to the bluff nature of these vehicles there is great potential for reducing drag with a simple add-on fairing.
