Experimental analysis of floating particle transport in turbulent flows

项目介绍

Experimentally investigate the clustering behaviour of floating particles and its link to the underlying flow features, in free surfaces lightly deformed by subsurface turbulence.

Job description

Climate action and life below water are two of the UN Sustainable development goals for this decade, the UN Decade for Ocean Sciences and Ocean transport thus Ocean transport and pollution have been identified as one of the Grand Challenges in Environmental Fluid Mechanics by the scientific community. Pollutant dispersion in aquatic environments (and in particular oil and microplastic transport) is specifically singled out as the main focal point of action.

In this context, we are interested in the behaviour of floating particles in free surfaces lightly deformed by subsurface turbulence. The free surface deformation and the underlying turbulent fields have a direct influence on particle transport with strong particle clustering behaviour observed in the case of floating particles.

In this PhD project you will work on developing state-of-the-art experimental and analytical tools in order to establish links between turbulent features and floating particle behaviour. Results from this study will provide a benchmark supporting further research on this topic (effects of particle inertia and buoyancy, surface contamination, wave forcing). Both particle image velocimetry (PIV) and particle tracking velocimetry (PTV) will be employed; while PIV measurements will provide information on the subsurface turbulence features, Lagrangian tools are needed for accurate tracking of material transport, especially with respect to marine pollution.

As a PhD student, you will be part of a vibrant team of researchers in the Fluid Dynamics and Multiphase Systems groups, with diverse backgrounds and expertise. You will be supervised by Assistant prof. Angeliki Laskari and Prof. Christian Poelma from the Multiphase systems group. The group is part of the Process & Energy Department, which aspires to conduct world-class research & education focusing on process & energy technologies for sustainable development. The research is conducted from a deep understanding of the underlying physics and is oriented towards industrial applications and societal needs. 

Requirements

You should have the following qualifications:

  • MSc. degree in mechanical, maritime, aerospace engineering, applied physics or a closely related field.
  • Strong background in fluid mechanics, ideally with experimental experience.
  • Strong mathematical/computational background (Matlab, Python).
  • Fluent communication skills in English, both in written and oral.

Conditions of employment

TU Delft offers PhD-candidates a 4-year contract, with an official go/no go progress assessment after one year. Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities, increasing from € 2395 per month in the first year to € 3061 in the fourth year. As a PhD candidate you will be enrolled in the TU Delft Graduate School. The TU Delft Graduate School provides an inspiring research environment with an excellent team of supervisors, academic staff and a mentor. The Doctoral Education Programme is aimed at developing your transferable, discipline-related and research skills.

The TU Delft offers a customisable compensation package, discounts on health insurance and sport memberships, and a monthly work costs contribution. Flexible work schedules can be arranged. For international applicants we offer the Coming to Delft Service and Partner Career Advice to assist you with your relocation.
