Call Postdoctoral fellow positions

Complete the following questionnaire for - IC2019_Summer Postdoctoral Fellowship in CFD modelling of seabed-fluid-structure interaction with application to offshore mooring systems  (239 KB)

Topic: Computational Fluid Dynamics modelling of seabed-fluid-structure interaction with application to offshore mooring systems

Applications are invited for a postdoctoral position in the CFD group (Ikerbasque Prof. Marco Ellero) at BCAM. The focus of the project will be on the accurate modelling of the interaction of submerged structures with complex rheological fluids representing seabed sediments. The latter feature is critical for the stabilization of floating platforms (e.g. offshore wind turbines) and the design of improved anchoring technologies for marine applications.

A novel aspect of this project will be represented by the simulation of the fluid-structure interaction with the soft soil phase. This is a complex liquid-solid material (e.g. sands, clay etc.) formed by a suspension of fine particles in water. A varying concentration of the dispersed phase can lead to different complex rheological behaviour ranging from yield-stress, shear-thinning and viscoplastic effects. For a quantitative description of the full structure-fluid-seabed interaction problem, an accurate multiphase non-Newtonian model is required.

The candidate will develop a multiphase model based on the meshless Smoothed Particle Hydrodynamics method to study several drag-embedded anchoring systems interacting with seabeds under different loading conditions. Simulation results will be validated against experimental data for scaled-down systems reproduced in the water tank facilities available at the Department of Fluid Mechanics at the University of the Basque Country (UPV/EHU).

The project will be performed in collaboration with the Nuclear Engineering and Fluid Mechanics Department and the Geodynamics Department (UPV/EHU) and Tecnalia Research & Innovation.


Deadline: August 20th 2019, 14:00 CET. (UTC+1) .

Applications will be evaluated in a continuous manner, with a response period no longer than 4 weeks after the call deadline .
