Job description

We are seeking a PhD candidate to join the von Karman Institute in the Department of Turbomachinery and Propulsion.

The proposed PhD project regards the experimental characterization of the unsteady aerodynamics of future high-speed low-pressure turbines.

One of the key technologies to enable efficient Ultra-High By-Pass ratio geared turbofans is the low-pressure turbine (LPT). While the geared engine architecture allows a large reduction in LPT stage count and weight, the LPT operates at transonic exit Mach numbers and low-Reynolds numbers. Within this range of operating conditions, there is a critical shortage of aerodynamic and performance measurements. The lack of relevant experimental data in these engine-like conditions also extends to the interaction of the secondary-air and leakage flows with the mainstream.

The present doctoral project contributes to filling up this gap with an extensive experimental undertaking that investigates the aerodynamics of high-speed LP turbines with detailed flow measurements in two world-class turbine rigs: a large scale, transonic, low-Reynolds number linear cascade including periodic incoming wakes, and a high-speed 1.5 stage turbine rig. Within the doctoral research project, the candidate will develop and implement specific measurement techniques for the turbine rigs. The successful candidate will contribute to the turbine experiment design, and will support the measurement campaign as an integral member of the turbine laboratory team. She or he will then study in detail the experimental data to analyse the loss generation mechanisms and the 3D unsteady interactions between secondary and mainstream flows.

One of the key goals of this doctoral project is the dissemination of the research findings to the scientific community through conference participation and peer-reviewed articles.

Requirements

You will have a Master in science (or near completion) in Mechanical Engineering, Aeronautical/Aerospace Engineering, or related engineering field. Successful applicants will ideally have graduated with an undergraduate Masters first class degree and MSc distinction/honours (or equivalent ranking).

A background and experience in the following subjects is essential: fluid dynamics, fundamentals of turbomachinery flows, heat transfer, measurement techniques, numerical methods for CFD. Knowledge of data-processing programming languages (such as Python or Matlab) is also a requisite.

Familiarity with pressure measurement techniques and/or optical techniques is an asset.

Working knowledge of CAD software (such as CATIA, SOLIDWORKS, etc.) and LabView is also an asset. Fluent knowledge of English (oral and written) is mandatory.

Candidates are expected to be self-motivated, hardworking and team players.

Conditions of employment

The appointment is for a period of 3 to 4 years, with an intermediate evaluation after two years, resulting in a PhD thesis. An educational plan will be drafted that includes attendance of courses, participation to international conferences and workshops, short stays in an external lab/university.

We maintain a very friendly and international working environment, which will provide easy adaptation for the selected applicant. We ensure a high- level of interaction in a world-known international research center specialized in fluid dynamics for aerospace, environmental and propulsion applications.

Additional information

p>The supervisors of the PhD project will be Prof. Sergio Lavagnoli and Prof. Tony Arts. Informal enquiries may be addressed to lavagnoli@vki.ac.be

You will be required to upload a covering letter, curriculum vitae, academic records (complete list of university courses with grades) for both M.Sc. and B.Sc. degrees, and the contact of two referees as part of your application. An interview including a scientific presentation will be part of the selection process. Selected candidates will be also asked to perform a technical exercise within a short deadline (1-2 weeks) in preparation of the interview.

This position is ONLY open to citizens of member countries of EU or NATO.

Applications should be sent through the VKI online application system.
