Leading Edge Separation Analysis of Oscillating Airfoil Energy Harvesters

Creator:

Ngo, Vickie

Abstract:

Oscillating foil energy harvesters are analyzed at optimal reduced frequencies (𝑘=𝑓𝑐/𝑈) to determine how the leading edge radius of curvature affects leading edge separation. The understanding of leading edge separation and its behaviors is critical to predicting the transient lift profile of an airfoil. The separation is therefore also critical...

Study of Energy Harvesting Performance of Oscillating Airfoils using a Discrete Vortex Model

Creator:

Kamrani Fard, Kiana

Abstract:

The energy harvesting performance of oscillating airfoils is studied using a discrete vortex model (DVM) with a leading-edge separation criterion. The airfoil undergoes a combined sinusoidal heaving and pitching motion at reduced frequencies of k = 0.06 − 0.16, with heaving amplitude of h0 = 0.5c, and pitching amplitude of...

Mechanically Enhanced and Optically Compatible Hydrogels for Particle Image Velocimetry in Porous Flow

Creator:

Cornwell-Arquitt, Luke

Abstract:

Hydrogels have been attractive for use as a medium in porous flow studies, but have always been limited in this role because of their poor mechanical properties. This project analyzes and tests two recently developed hydrogels, poly(methacrylamide-co-methacrylic acid) (PMM), and a heat-treated long chain PVA hydrogel. Particle image velocimetry (PIV)...
