Offer Description
If you are establishing your career as scientist and you are looking for the best possible foundation for fulfilling your dreams and ambitions, this is your chance.
We offer the best possible training for you to become a mature top-level researcher giving you excellent career opportunities both in academia and industry.
The green transition of energy systems requires the implementation of novel emerging energy conversion technologies based on turbomachinery with two-phase flow. However, the current level of knowledge and understanding of two-phase flow in turbomachinery is low, urgently calling for the need of educating scientists that can support the development of such technologies.
In this context, as part of a recently started MSCA-DN (Marie Skłodowska-Curie Actions, Doctoral Network) project on two-phase flow in turbomachinery entitled “Training42Phase”, Exergy International currently has one opening for a PhD position with focus on aero-thermodynamics.
The aim of Training42Phase is to educate the future leading scientists within turbomachinery with two-phase flow, thereby providing the scientific and technological basis required for the development of the next generation of turbomachinery. Within this project you will get the chance break new ground at the absolute forefront of what is possible. You may read more about the Training42Phase project here at https://training42phase.dtu.dk/ .
The other project partners recruiting PhD students are Technical University of Denmark, (four PhD positions with focus on aero-thermodynamics), Politecnico di Milano, Italy (two PhD positions with focus on aero-thermodynamics), CentraleSupélec, France (three PhD positions with focus on reliability and maintenance), and Imperial College of Science Technology and Medicine, UK (two PhD positions with focus on structural mechanics). The project also includes other industrial partners from large international companies and SMEs.
Responsibilities/ object of the research
The research will be focused on the design and optimization of an axial – centrifugal pump stage for boiling Organic Rankine Cycle (ORC) fluid with the aim to:
1) Develop a thermodynamic model suitable to predict fluid dynamic behaviour of ORC condensate fluid at the onset boiling threshold;
2) Develop numerical methods to predict the formation of bubbles/droplets at the pump inducer;
3) Design and evaluate different concepts/geometries of the pump stage with the target to mitigate any cavitation phenomena, considering also blade erosion and reliability;
4) Evaluate the performance of the design via numerical tools and scaled model test to assess onset cavitation at different fluid conditions both for its thermodynamic status as well as for distortions that might arise from upstream equipment. The performance assessment shall define the expected operating characteristics of the pump and the preferred regulation and flow control strategy
The expected results:
1) Conceptual design for a high-efficiency low-cavitation pump centrifugal stage for the use in ORC feed pump service with zero net positive suction head;
2) Identify the methods to cavitation energy in centrifugal pump inducers;
3) Prepare a conceptual design for pump stage suitable for low / zero net positive suction head in ORC applications.
