Navier–Stokes analysis of lift-enhancing tabs on multi-element airfoils

Multi-Fidelity High-Lift Aerodynamic Optimization of Single-Element Airfoils

We describe a computationally efficient simulation-driven design methodology for single-element airfoils at high-lift conditions. Direct optimization of an accurate but computationally expensive high-fidelity simulation model based on Reynolds-Averaged Navier-Stokes equations is replaced by iterative updating and re-optimization of a cheap surrogate. The surrogate model exploits a low-fidelity ...

Designing high-lift airfoils using genetic algorithms

A multi-component airfoil design procedure is presented. It is based on a multi-objective genetic optimizer coupled with a boundary layer flow field solver capable of working in high-lift conditions. Examples of unconstrained and constrained lift coefficient maximization are reported.

A Multifidelity Multiobjective Optimization Framework for High-Lift Airfoils

High-lift devices design is a challenging task as it involves highly complex flow features while being critical for the overall performance of the aircraft. When part of an optimization loop, the computational cost of the Computational Fluid Dynamics becomes increasingly problematic. Methods to reduce the optimization time has been of major interest over the last 50 years. This paper presents a...

Aerodynamic Analysis of Wind Turbines Rotors with High Lift Airfoils by Using Pre-conditioned WENO Scheme

The aerodynamic analysis of wind turbine rotors using preconditioned weighted essentially non-oscillatory scheme to solve the compressible NavierStokes equations in non-inertial coordinate system with Spalart-Allmaras one equation turbulence model is presented. A parallel clustering algorithm based on Message Passing Interface library was implemented. The NREL Phase VI rotor with S809 airfoil w...
