State-of-the-art in aerodynamic shape optimisation methods [PDF]
Aerodynamic optimisation has become an indispensable component for any aerodynamic design over the past 60 years, with applications to aircraft, cars, trains, bridges, wind turbines, internal pipe flows, and cavities, among others, and is thus relevant ...

Efficient Aerodynamic Shape Optimization [PDF]
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).

An aerothermodynamic design optimization framework for hypersonic vehicles [PDF]
In the aviation field great interest is growing in passengers transportation at hypersonic speed. This requires, however, careful study of the enabling technologies necessary for the optimal design of hypersonic vehicles.

Rapid aerodynamic shape optimization under uncertainty using a stochastic gradient approach
A common approach in aerodynamic design is to optimize a performance function—provided some constraints—defined by a choice of an aerodynamic model at nominal operating conditions.

Simultaneous pseudo‐time stepping for aerodynamic shape optimization [PDF]
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.

A CFD-informed quasi-steady model of flapping-wing aerodynamics [PDF]
Aerodynamic performance and agility during flapping flight are determined by the combination of wing shape and kinematics. The degree of morphological and kinematic optimization is unknown and depends upon a large parameter space.

Aerodynamic shape optimization of a low drag fairing for small livestock trailers [PDF]
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.

Data-driven aerodynamic shape design with distributionally robust optimization approaches [PDF]
We formulate and solve data-driven aerodynamic shape design problems with distributionally robust optimization (DRO) approaches. Building on the findings of the work \cite{gotoh2018robust}, we study the connections between a class of DRO and the Taguchi ...
