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).

Aerodynamics-assisted, efficient and scalable kirigami fog collectors [PDF]
Nature Communications, 2021 AbstractTo address the global water shortage crisis, one of the promising solutions is to collect freshwater from the environmental resources such as fog. However, the efficiency of conventional fog collectors remains low due to the viscous drag of fog-laden wind deflected around the collecting surface.

Flight Test Maneuvers for Efficient Aerodynamic Modeling [PDF]
Journal of Aircraft, 2011 Novel flight test maneuvers for efficient aerodynamic modeling were developed and demonstrated in flight. Orthogonal optimized multi-sine inputs were applied to aircraft control surfaces to excite aircraft dynamic response in all six degrees of freedom simultaneously while keeping the aircraft close to chosen reference flight conditions.

CFD Investigation of Dual Synthetic Jets on an Optimized Aerofoil's Trailing Edge [PDF]
Journal of Applied Fluid MechanicsIn fluid dynamics, a flow control device is used to control, manage, or modify the behavior of a fluid flow. Jet actuators work by releasing high-velocity jets of fluid, usually air or gas, into the surrounding environment to control or manipulate the ...
