Horizontal Axis Hydroturbine Shroud Airfoil Optimization

, 2014
The present work concerns the optimization of the shroud of an horizontal axis hydro turbine (HAHT). The main aim is to improve the hydro-turbine efficiency by designing a new shroud airfoil through an optimization process that maximize, as objective function, the power coefficient.

Airfoil optimization by Evolution Strategies

2013 IEEE Congress on Evolutionary Computation, 2013
This paper addresses subsonic airfoil optimization using Evolution Strategies (ES) and devises a means of defining the airfoil geometry that reduces unnecessary restrictions in the search space. The solution encoding uses Bezier Control Points to define the geometry of the airfoil, but does not restrict the movement of the control points as was common ...

Airfoil design by optimization

Journal of Aircraft, 1977
An airfoil design technique is described which uses an analytical method for representing the airfoil contour by Wagner functions and a computational procedure for obtaining the values of the coefficients of expansion. The method for approximating an airfoil contour by a Fourier-type series of Wagner functions is briefly outlined, and a flow chart for ...

Nonsinusoidal Path Optimization of a Flapping Airfoil

AIAA Journal, 2007
The path of a flapping airfoil undergoing a combined, nonsinusoidal pitching and plunging motion is optimized for maximum thrust and/or propulsive efficiency. The nonsinusoidal, periodic flapping motion is described using nonuniform rational B splines. A gradient based algorithm is then employed for the optimization of the nonuniform rational B-spline ...

Airfoil Design and Optimization

ZAMM - Journal of Applied Mathematics and Mechanics / Zeitschrift für Angewandte Mathematik und Mechanik, 2001
AbstractThe aerodynamic efficiency of mildly swept wings is mainly influenced by the characteristics of the airfoil sections. The specific design of airfoils is therefore one of the classical tasks of aerodynamics. Since the airfoil characteristics are directly dependent on the inviscid pressure distribution the application of inverse calculation ...

Shape Optimization for Conforming Airfoils

44th AIAA/ASME/ASCE/AHS/ASC Structures, Structural Dynamics, and Materials Conference, 2003
Interest in the design and development of unmanned aerial vehicles (UAVs) has increased dramatically in the last two and a half decades. The Buckle-Wing UAV concept being developed in this research is designed to “morph” in a way which facilitates variations in wing loading, aspect ratio and wing section shapes.
