Personal profile

Scholarly biography

Cyril Crua is a Professor at the Sir Harry Ricardo Laboratories within the Advanced Engineering Centre. He has 20 years’ experience in optical and laser-based diagnostics for experimental fluid dynamics, with a focus on spray formation and combustion.

Research interests

My research focuses on experimental fluid dynamics, and particularly on the development of optical diagnostic techniques to investigate the physics of complex flows and atomisation. My current research interests include:

  • Optical diagnostic techniques for sprays and combustion
  • Spray formation and breakup
  • Microscopic imaging of sprays
  • Experimental fluid dynamics

Supervisory Interests

I am interested in supervising postgraduate research students in experimental fluid dynamics, including the development of optical measurement techniques for atomisation and other complex flows. These subjects are often linked to applications in energy (fuel efficiency, energy recovery, carbon capture), manufacturing (Minimum Quantity Lubrication) and medical devices (bioartificial organs, optical implants).

Since joining the University of Brighton I have supervised 1 MPhil and 12 PhDs to completion, and examined 20 PhDs in the UK, France, Denmark, Malaysia, and Australia. I am currently supervising 4 PhD students researching spray systems.
