PhD Position Two-Phase Flow Turbulence Measurements and Modelling

Bubbly flows may be a key to ship emission reduction and much more, but first we need to expand our understanding and modelling capability of these complex multi-physical systems.  

Bubbly two-phase flow is a typical and important feature of marine hydrodynamic applications as well as many other fields. From air entrained at the free surface due to breaking waves and water entry, to cavitation on propellers and high speed hydrofoils, and even drag reduction devices which could reduce shipping emissions.
Accurate modelling of mixed two-phase flows is challenging even before considering that real applications are typically turbulent and take place in saltwater, making this a true multi-physics problem.

The PhD candidate on this project will study these flows, using experimental facilities, direct numerical modelling, and statistical analysis. TU Delft has a range of appropriate experimental facilities including a new cavitation tunnel capable of running saltwater experiments. TU Delft has also opened its new two-petaflop DelftBlue supercomputer and the PhD candidate will have access to a validated direct numerical simulation two-phase flow solver for fresh water. The goal of the project will be to use and extend these tools to build a better understanding of turbulent two-phase flows, particularly in saltwater. 

Need-to-haves

• Bachelors and Masters level degree in technical field (Engineering, Mathematics or Physics)
• Expertise in fluid mechanics

Nice-to-have

• Experience with two-phase flow, computational fluid dynamics modelling, statistical methods, and experimental methods.

Doing a PhD at TU Delft requires English proficiency at a certain level to ensure that the candidate is able to communicate and interact well, participate in English-taught Doctoral Education courses, and write scientific articles and a final thesis. For more details please check the Graduate Schools Admission Requirements .

Doctoral candidates will be offered a 4-year period of employment in principle, but in the form of 2 employment contracts. An initial 1,5 year contract with an official go/no go progress assessment within 15 months. Followed by an additional contract for the remaining 2,5 years assuming everything goes well and performance requirements are met.

Salary and benefits are in accordance with the Collective Labour Agreement for Dutch Universities, increasing from € 2541 per month in the first year to € 3247 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.
