Research Associate in Advanced Laser Diagnostics Investigating the Fluid Mechanics of Primary Breakup

The University of Edinburgh

Location: Edinburgh
Salary: £37,099 to £44,263
Hours: Full Time
Contract Type: Fixed-Term/Contract
Placed On: 1st February 2024
Closes: 7th March 2024
Job Ref: 9577

The Opportunity: 

This Research Associate position will contribute to the project ‘Unresolved fluid mechanics at liquid/gas interfaces for primary breakup of atomizing sprays’ within the Institute of Multiscale Thermofluids at the University of Edinburgh, which is funded by the European Research Council and in collaboration with colleagues at RWTH Aachen University and Sandia National Laboratories.

This project focuses on experimental measurements that help address unresolved questions related to the fluid dynamics at liquid/gas interfaces (LGI) associated with primary breakup. We will image LGIs using pulse-burst Ballistic Imaging as well as Two-Photon Laser Induced Fluorescence. Those methods will be combined with wavelet-based Optical Flow (wOF) to resolve velocity and acceleration of liquid fluid at the LGI as the liquid core breaks into primary drops. These advanced methods will be combined with traditional in-nozzle imaging (e.g., shadowgraphy, Schlieren). These methods will be applied to a variety of sprays emitted from enlarged transparent, as well as real sized nozzles (100’s of microns). Primary break up will be studied for a wide range of Reynolds, Weber and Cavitation number, and serve as relevance to a variety of spray applications (e.g., agricultural, medical, or combustion). 

We are hiring a PDRA with experience with laser diagnostics in sprays. Candidates with experience using optical flow (or similar), combined with experimental fluid mechanics will also be considered. Candidates without experience with laser diagnostics will not be considered. Strong candidates will exhibit the ability to learn new diagnostics and image processing methods (e.g., wOF) and apply them to optically dense sprays. Candidates must have their PhD in Engineering or other relevant fields.

This role is UE07 and is available on a fixed term basis for up to 48 months.

A full list of main responsibilities and the knowledge, skills and experience required for the role can be found in the full job description below.

Your skills and attributes for success: 

  • Proven track record with laser diagnostics for fluid mechanic research
  • Experience in spray research
  • Strong track-record in publishing in peer reviewed scientific journals
  • Experience or theoretical knowledge of optical flow
  • Strong understanding of fluid mechanics and multiphase flows
