Experimental Geometry Optimization Techniques for 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 ...

Multi-objective Evolutionary Optimization of Subsonic Airfoils

This work concerns the application of multi-objective evolutionary optimization by approximation function to 2D aerodynamic design. The new general concept of evolution control is used to on-line enriching the database of correct solutions, which are the basis of the learning procedure for the approximators. Substantially, given an initial very poor model approximation, which means small size o...

Semi-Parametric Techniques for Multi-Response Optimization

Genetic algorithm for multi-objective experimental optimization

A new software tool making use of a genetic algorithm for multi-objective experimental optimization (GAME.opt) was developed based on a strength Pareto evolutionary algorithm. The software deals with high dimensional variable spaces and unknown interactions of design variables. This approach was evaluated by means of multi-objective test problems replacing the experimental results. A default pa...

OCTAVIS: Optimization Techniques for Multi-GPU Multi-View Rendering

We present a high performance—yet low cost— system for multi-view rendering in virtual reality (VR) applications. In contrast to complex CAVE installations, which are typically driven by one render client per view, we arrange eight displays in an octagon around the viewer to provide a full 360◦ projection, and we drive these eight displays by a single PC equipped with multiple graphics units (G...
