Unsteady aerodynamic theory for membrane wings
Sonya Tiomkin, Justin W. Jaworski
We study analytically the dynamic response of membrane aerofoils subject to arbitrary, small-amplitude chord motions and transverse gusts in a two-dimensional inviscid incompressib…
On the noise generation and unsteady performance of combined heaving and pitching foils
Nathan Wagenhoffer, Keith W Moored, Justin W Jaworski
A transient two-dimensional acoustic boundary element solver is coupled to a potential flow boundary element solver via Powell's acoustic analogy to determine the acoustic emission…
Stability of Helical Vortex Structures Shed from Flexible Rotors
Steven N. Rodriguez, Justin W. Jaworski, John G. Michopoulos
The presented investigation is motivated by the need to uncover connections between underlying rotor fluid-structure interactions and vortex dynamics to fatigue performance and cha…
Unsteady aerodynamics of porous aerofoils
Peter J. Baddoo, Rozhin Hajian, Justin W. Jaworski
We extend unsteady thin aerofoil theory to model aerofoils with generalised chordwise porosity distributions. The analysis considers a linearised porosity boundary condition where…
Strongly-coupled aeroelastic free-vortex wake framework for floating offshore wind turbine rotors. Part 2: Application
Steven N. Rodriguez, Justin W. Jaworski
This two-part paper presents the integration of the free-vortex wake method (FVM) with an aeroelastic framework suitable to model the rotor-wake interactions engendered by floating…
Noncirculatory fluid forces on panels with porosity gradients
Rozhin Hajian, Justin W. Jaworski
This Note determines the unsteady non-circulatory forces on an arbitrarily deforming panel with a Holder-continuous porosity distribution. An analytical expression for the non-circ…
Thrust augmentation of flapping airfoils in low Reynolds number flow using a flexible membrane
Justin W. Jaworski, Raymond E. Gordnier
The unsteady aerodynamic thrust and aeroelastic response of a two-dimensional membrane airfoil under prescribed harmonic motion are investigated computationally with a high-order N…
Nonlinear Low-to-High Frequency Energy Cascades in Diatomic Granular Crystals
E. Kim, R. Chaunsali, H. Xu +4
We study wave propagation in strongly nonlinear 1D diatomic granular crystals under an impact load. Depending on the mass ratio of the `light' to `heavy' beads, this system exhibit…
