Vertical axis turbines, also called Darrieus turbines, present interesting characteristics for offshore wind and tidal applications but suffer from vibrations and a lower efficiency than the more conventional horizontal axis turbines. The use of vari

In this work, a collaborative experimental study has been conducted to assess the effect an imposed internal pressure has on the controlling the hydrodynamic performance of a compliant composite hydrofoil. It was expected that the internal pressure t

For the high-performance foiling yachts, cavitation is often a limiting factor for take-off and top speed. The present work investigates solutions to delay the onset of cavitation thanks to a combination of leading edge and trailing edge flaps. Both

The objective of this paper is to investigate wall-pressure fluctuations downstream of a Laminar Separation Bubble (LSB) on a laminar NACA66 hydrofoil section, based on Direct Numerical Simulation (DNS) and experimental analysis. DNS is performed usi

Marine lifting surfaces may undergo flow-induced vibrations due to fluid sources of excitation, leading to shorter life cycles due to structural fatigue and critical to the acoustic performances (e.g hydrofoil singing). As such, accurate understandin

Multivariate empirical mode decomposition (MEMD) has been introduced to make standard EMD suitable for direct multichannel signals processing. Unlike EMD, MEMD is able to align sifted intrinsic mode functions (IMFs) from multiple data channels. The a
