Pitching foil propulsion performance decays near the free surface
A series of experiments reveal the non-linear relationship between the propulsive performance of a pitching foil and its distance to the free surface. Efficiency dropped more than a 40% when the foil was placed at a distance of approximately 5 to 10% of the span of the system, as a consequence of a large decrease in thrust and a large increase in power, both clearly linked to wake formation.
The Laboratory for Fluid-Structure Interaction (LIFE) (https://labfsi.com/) of the Department of Mechanical Engineering at the Universitat Rovira i Virgili (URV) (www.urv.cat) in Tarragona (Spain), is looking for an enthusiastic research student with a strong interest in fluid dynamics and fluid-structure interactions. Successful candidates will join a small but very active multidisciplinary team, working in several fluid-structure interaction (FSI) problems. The research will be mainly experimental and focused FSI with application to several engineering problems. The main topic that will be considered during the research include but are not limited to “vortex-induced vibrations for energy harvesting applications”.
Applicants will enroll in the Inter-University PhD Programme in Fluid Mechanics (http://www.doctor.urv.cat/en/prospective-students/courses/7720/index/) in which the URV participates together with other Spanish Universities: U. Jaén, U. Politécnica de Madrid, U. Zaragoza, U. Carlos III Madrid y UNED.
CANDIDATES:
Successful applicants must hold a Master degree in Engineering (at least equivalent to a 5 years course in Engineering) at the time of the application, in the areas of Mechanical, Industrial, Aeronautical, Naval or Civil Engineering(note that other backgrounds might not be considered). Preference will be given to candidates able to demonstrate the following desired skills:
Matlab / Python / LabVIEW
Mechanical engineering design tools such as Inventor, Creo, etc.
Simulation tools such as OpenFOAM, NASTRAN, ANSYS,…
Experience with the use of optical measurement techniques, with emphasis in DPIV.
DETAILS AND APPLICATION PROCEDURE:
The call for applications will be opened from 12/01/2023 to 26/01/2023 and managed the Agencia Estatal de Investigación:
Stanford’s 2022 updated list identifies the top 2% most influential scientists in the world, overall and in each field of research. It was issued for the first time with 2019 data and now the list has been updated.
The team uses a new methodology that uses a wide range of parameters, instead of using only number of citations/H-index, that tends to favor very senior researchers and large research groups where publications are shared and mass produced, indirectly promoting production (large number of papers) over quality and impact. Here, parameters such as number of single authored papers, total cites to single authored papers, number of first authored papers, etc. are evaluated.
I am proud to appear in the list for the third time, since its first publication, and in all the updates!
Stanford’s 2020 updated list identifies the top 2% most influential scientists in the world, overall and in each field of research. It was issued for the first time with 2019 data and now the list has been updated with 2020 data.
The team uses a new methodology that uses a wide range of parameters, instead of using only number of citations/H-index, that tends to favor very senior researchers.
URV had 30 researchers in the list in 2019 and 38 researchers in 2021. I am very happy to appear in the list for two consecutive years in #FluidsPlasmas, based on the impact of my research in 2020!

The paper describes recent experiments showing the vortex-induced vibrations of a one degree-of-freedom cylinder, undergoing periodic forced rotations.
You can now download our most recent article, published in Applied Ocean Research. The paper describes experiments that show that the drag seen by plates in cross-flow near the free surface, can be reduced using serrations or holes at the plate’s edges.
