Mesoscopic flow modelling of complex particle suspensions

Applications are invited for two postdoctoral positions in mesoscopic modelling of complex suspensions at the CFD group (BCAM).

Many numerical techniques have been developed in the past decades to target suspensions with simple Newtonian solvents, however scarce results are available in the case of non-Newtonian matrices or morphologically-complex shapes. Building upon our previous work [1,2,3], the goal of this project is to design and further develop fully-resolved Smoothed Particle Hydrodynamics (SPH) models of particulate systems

(1) interacting with complex viscoelastic and thixoplastic suspending media and
(2) with complex anisotropic and highly-irregularly-shaped particles in suspension.

Focus will be on the specific particle dynamics (sedimentation etc.), as well the resulting rheological behaviour of the suspension and link to microstructure.

The postdoctoral candidate will work under the supervision of Ikerbasque Prof. Marco Ellero (CFD group, BCAM) on the developments and use of novel mesoscopic particle-simulation methods to better understand the fluid dynamics and rheology of complex suspensions. Close collaborations with technological centers in the Basque Country is expected (Leartiker, Tecnalia), where experimental data will be provided to calibrated and validate the models.
