We investigate whether applying an internal radiocarpal-spanning plate with the wrist in slight extension affects the biomechanical stability of the construct. An unstable distal radius fracture was simulated in 10 cadaveric specimens and immobilized

A data-driven hydrodynamic force model is developed to model the dynamic forces on an oscillating circular cylinder for flow conditions where Vortex-Induced-Vibrations (VIV) are known to occur. The model is developed for use in future control systems

Digital twins can be used as model representations of physical systems given adequate information about the physics through environmental measurements. For moving bodies in the presence of boundaries, knowledge of the local boundary conditions is nec

The effect of varying the structural mode excitation on bending-dominated flexible cylinders undergoing vortex-induced vibrations was investigated. The response of the bending-dominated cylinders was compared with the response of a tension-dominated

We study the use of small counter-rotating cylinders to control the streaming flow past a larger main cylinder for drag reduction. In a water tunnel experiment at a Reynolds number of 47 000 with a three-dimensional and turbulent wake, particle image

A series of experiments was performed to investigate the modal excitation of a tensioned flexible cylinder in a uniform flow due to flow-induced vibrations. Experiments were conducted in a recirculating flow channel using a flexible cylinder with rel

The modal structure of a tension-dominated flexible cylinder undergoing vortex-induced vibrations in a uniform current is investigated through multivariate analysis. Experiments are performed in a recirculating flow channel where a flexible cylinder

A detailed series of experiments is performed to investigate the ‘ground effect’ experienced by propulsive flapping foils operating near a solid boundary. A high aspect ratio foil is towed at constant speed and oscillated in pitch and heave at va

In this study, piezo stripe actuators were used to control the vibrations of a flexible cylinder undergoing underwater flow-induced vibrations. The piezo actuators were attached at the anti-nodes of a rectangular plastic beam and urethane rubber was
