An extension of pseudo-3D vortex particle methods for aeroelastic interactions of thin-walled structures

Samir Chawdhury et al.

Summary: This paper introduces an extension of VPM for the complex aeroelastic interactions of thin-walled structures, presenting a new coupled model that includes 3D shell vibration modes for structural analysis. The effectiveness of the coupled method is demonstrated through validation of critical flutter wind speed and studying aeroelastic flapping of different flexible plates.

A circle theorem technique to handle 2-D flows around arbitrary cylinders in discrete vortex method

Guoqing Jin et al.

Summary: The study introduces a novel boundary method to handle the leaking of vortex blobs by introducing identical vortices outside the body based on the circle theorem technique. This method maintains the streamlined body surface and conserves total circulation at each time step. Numerical simulations demonstrate good agreement between the new technique predictions and experimental results in predicting hydrodynamic loads.

Flow-induced cross-flow vibrations of long flexible cylinder with an upstream wake interference

Ke Lin et al.

Summary: This study numerically investigates the flow-induced vibration (FIV) of a flexible cylinder with an upstream wake interference at a subcritical Reynolds number. The dynamic response of the cylinder FIV with the upstream wake interference is characterized and the interaction mechanisms responsible for the structural dynamic response are elucidated. Results show that the FIV response with upstream wake interference exhibits distinct features from isolated vortex-induced vibration, including larger amplitude vibration during modal resonance branch transition and extension of the modal resonance branch.
