Job description

Unsteady aerodynamic forcing affects the operation of a wide variety of natural, biological, and industrial systems: from insect flight to wind turbines. These forces can be understood in terms of simplistic, quasi-steady assumptions, which are inaccurate but interpretable, or they can be predicted via computationally intensive numerical methods which are accurate but do not always provide physical insight. This project will explore methods for incorporating unsteady time-history effects in interpretable low-order models for aerodynamic force prediction.

This four-year PhD project will develop methods for the identification of the dependence of instantaneous forces experienced by unsteadily oscillating bodies, such as the wings of insects or the blades of a wind turbine, on their kinematic time history. The focus will initially be on kinematics related to the flapping flight of insects, because of the complex reciprocating motion they employ and commensurately complex interplay of force-producing mechanisms. The ultimate goal is to develop both physical understanding of the aerodynamic mechanisms involved in wing-wake interaction and a methodology for nonlinear time-dependent system identification which can be more broadly applied to unsteady industrial flows in, for example, wind energy and aerospace applications.

The approach taken will be based on the generation and analysis of experimental data, using a unique unsteady flows facility which combines advanced flow diagnostic methods, including particle image velocimetry (PIV), with industrial robotics hardware. Working from a sufficient database of experimental flow and force measurements, the functional dependence of force on kinematic history in a lower-order space will be regressed. Possible means of performing this data analysis include techniques from dynamical systems theory and machine learning: For example, the extended dynamic mode decomposition or Volterra series representation.

The PhD student will be hosted by the Faculty of Mechanical, Maritime, and Materials Engineering (3mE) of TU Delft, within the Fluid Mechanics group of the Energy, Flow, and Process Technology department and will have the opportunity to collaborate with our partners at the Wageningen University Experimental Zoology group.

Requirements

We are looking for a candidate with an MSc degree (or equivalent) in a field related to Aerodynamics, Fluid Mechanics, Mechanical Engineering, Applied Mathematics. Experience in the fields of Biomechanics or Systems and Control would also be valued.

The candidate is expected to have the following skillset:

  • A strong background in fluid mechanics or aerodynamics (eg. turbulence, unsteady flows, biopropulsion).
  • Experience with experimental flow measurement techniques (eg. particle image velocimetry).
  • Scientific computing and programming skills are necessary (eg. C/C++, Python, Matlab).
  • A good command of the English language is required.
  • Experience with data-driven analysis or system identification techniques (eg. dynamic mode decomposition) is a plus.

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 .


Conditions of employment

Fixed-term contract: 4 years.

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.
