PhD Studentship: Experimental Investigation of Flow-Induced Vibrations of Flexible Structures

Newcastle University - School of Engineering

Value of award

The award is worth £18,500 pa contributing towards tuition fees and tax-free stipend. Additional funding is available for experimental works and professional developments (e.g. conferences). International candidates will be required to make up the difference between UK/EU and international fees.

Start date and duration: 1 February 2018 (or thereafter as soon as possible), for 3.5 years.

Application closing date: 15 January 2018.


In nature, fluid flows create hydrodynamic force excitations and vibrations of engineering structures. This project will focus on experimental investigations of flow-induced vibrations of flexible structures transporting internal flows and subject to external waves/currents.

This project aims to advance fundamental and theoretical understanding of fluid-structure interaction phenomena for flexible cylindrical structures subject to combined hydrodynamic excitations from external/internal flows, with applications to offshore subsea oil and gas, renewable energy and mining industrial sectors. The successful candidate will work alongside the EPSRC-funded project 'MUltiphase Flow-induced Fluid-flexible structure InteractioN in Subsea applications (MUFFINS), and collaborate with a multidisciplinary team of international researchers, academics and industrial partners.

Specifically, the key objectives of this project are to:

  • Develop novel experimental frameworks and measurement in fluid flows for the current-wave water flume facilities at the School of Engineering’s Hydrodynamics Laboratory.
  • Investigate vortex-induced vibration (VIV) phenomena due to current flows.
  • Investigate combined effects of VIV and unsteady-flow wave excitations.
  • Investigate internal (single/multiphase) flow effects on the transporting flexible pipes.
  • Investigate overall fluid-structure interactions due to combined VIV/wave/internal flows.
  • Develop software codes for experimental calibration, sensitivity, post-processing, error and uncertainty analyses.
  • Compare experimental results (structural dynamics and hydrodynamic forces) with in-house mathematical models and simulation tools.
  • Publish research journal papers and disseminate outputs through international/national conferences and project meetings.

You will join and work closely with the ‘Fluid-flexible structure iNterAction ReseArch (FlexNARA)’ team, and you will have opportunity to visit collaborators at the National University of Singapore or University of Sao Paulo in Brazil. For further information, please visit
