title = "Numerical and experimental study of a fluttering membrane strip",
abstract = "The paper presents a numerical and experimental aeroelastic study of a membrane strip in low speeds, motivated by the Windbelt energy harvesting device. Flutter and divergence speeds are computed using both the strip theory and panel aerodynamic models, and a structural modal model of the preloaded membrane strip. A wind-tunnel experiment is set up and serves as a reference to the numerical models. The computed flutter speeds and frequencies are in reasonable agreement with wind tunnel data, indicating that linear flutter analysis is adequate for study of the flutter characteristics of a membrane strip. A parametric study of membranes of various preloads and added masses demonstrated that it is possible to tune the flutter speed to a desired range of flow velocities, thus optimizing a Windbelt device to the expected wind speeds. Discrepancies between the computed and wind-tunnel flutter speeds are attributed to the aerodynamic modeling, which is likely not suitable for zero-thickness configurations in low Reynolds speeds.",
