Efficient Aerodynamic Design Method Using a Tightly Coupled Algorithm
AIAA Journal, 2000An efe cient aerodynamic design optimization method for the compressible Euler equations is presented. A gradient-based optimization method is used to e nd the optimal design, in conjunction with a continuous adjoint sensitivity analysis method. To improve the efe ciency of the design method, a tightly coupled algorithm based on a step-size estimation ...

Aerodynamic Perspectives on Wind Energy Efficiency
2019This thesis investigates the efficiency of wind energy conversion from three aerodynamic perspectives. The first, purely theoretical, assumes steady inviscid flow conditions to identify multi-rotor setups that can extract more power per unit area than isolated rotors.

An Analytical–Numerical Aerodynamic Formulation for Efficient Aeroacoustics Analysis of Rotorcraft
ASME 2012 Noise Control and Acoustics Division Conference, 2012This paper presents an analytical-numerical aerodynamic/aeroacoustic formulation for the analysis of the tonal noise emitted by helicopter rotors and propellers. It is particularly suited for those configurations dominated by local high-frequency changes (both in time and space) of blades inflow velocity.

On the sensitivity and efficiency of aerodynamic shape optimisation [PDF]
, 2019 Computational fluid dynamics (CFD) has become the method of choice for aerodynamic shape optimisation of complex engineering problems. To date, however, the sensitivity of the optimal solution to numerical parameters has been largely underestimated. Meanwhile, aerodynamic shape optimisation based on high-fidelity CFD remains a computationally expensive
