PhD position in computational fluid dynamics (CFD)

Project Outline

This project aims to understand the physics behind the coupling of flow and acoustics disturbances in the separated shear layer and wake by means of Direct Numerical Simulation (DNS). Furthermore, new correlations to characterise the impact of turbulent disturbances on the shear-layer breakdown and the acoustic feedback loop mechanism on laminar-to-turbulent transition in high-subsonic and transonic flows will be developed.

Further Project Information

• Primary investigation of low-Reynolds-number flows subjected to turbulent and/or acoustic disturbances.
• Conduct DNS simulations in HIPSTAR code and implement acoustic excitation procedures.
• Conduct stability analyses and develop correlations describing the breakdown of the separated shear layer under turbulent and acoustic forcing, as well as the influence of the acoustic feedback loop on mean-flow transition in compressible flows.
• Consult obtained results with supervisors, publish findings in scientific journals, present results at conferences, and prepare a PhD thesis.

Eligibility Criteria

• Demonstrate outstanding qualities and be motivated to complete the PhD within 4 years.
• Master's degree in relevant engineering, applied mathematics, or physics.
• Solid knowledge of, and experience in, the mathematical and numerical simulation of turbulent flows.
• Strong academic profile in engineering, maths, or applied mathematics.
• Fundamental knowledge and understanding of fluid mechanics, numerical methods, turbulence, and acoustics.
• Strong programming skills (Python, C/C++, Fortran).
• Experience with Fortran is considered an advantage.
• Fluency in English is required.

We Offer

• A three-month training program focusing on the use and further development of the high-quality HiPSTAR code at the University of Melbourne, Australia.
• Participation in highly regarded international scientific conferences.

Required Documents

• Curriculum Vitae (CV)
• Motivation Letter
• Master's diploma and transcript of records
• Research interests statement (1–2 pages)
• DOI or copies of scientific publications (if available)
• English language certificate (if available)
• Contact details of two academic referees

Selection Procedure

• Evaluation of academic achievements according to regulations by NCN.
