PhD Position to work in the challenging MSCA Doctoral Network ABHSSYS – Vibroacoustic control of fluid-filled pipes with add-on acoustic black holes

ABHSSYS (Acoustic Black Holes for Silent SYStems, Grant agreement ID: 101227712) is a European Doctoral Network funded by the Marie Skłodowska-Curie Actions (MSCA), dedicated to advancing innovative solutions for vibration and noise control in lightweight structures (https://cordis.europa.eu/project/id/101227712). The project focuses on the development of Acoustic Black Hole (ABH) technologies, an emerging concept that enables efficient damping of vibrations and sound while reducing mass and material use. Bringing together leading academic laboratories and industrial partners across Europe, ABHSSYS will train a new generation of researchers at the interface of wave physics, acoustics and engineering. Through interdisciplinary research, international mobility and close collaboration with industry, the programme aims to accelerate the transfer of ABH technologies towards real-world applications in sectors such as aerospace and energy.

The propagation of noise and vibrations in hydraulic systems is a critical issue across numerous industrial sectors, including building services, energy, and aerospace. Noise sources are primarily linked to hydraulic pumps generating pressure pulsations in the circuit. Structural vibrations can lead to mechanical fatigue, particularly at pipe junctions, with potentially serious consequences for the operation and safety of hydraulic installations.
Furthermore, acoustic waves propagating inside the pipe can be a source of noise disturbance, especially in building-related applications. Developing effective devices to control the propagation of vibrations and acoustic waves in pipes is therefore of primary importance. (…)
