Mr

Jonathan Connolly MEng

Postdoctoral Research Assistant

Biography

Jonathan attended St Edmund Hall, where he studied for his MEng in Engineering Science, before transferring to Wolfosn College for his DPhil as part of the EPSRC CDT in Gas Turbine Aerodynamics. The focus of his doctoral research was the analysis of ice crystal icing in gas turbine engines.

He is now a Postdoctoral Research Assistant in the Particle Deposition Group, working on the ingestion of both ice crystals and volcanic ash in gas turbines.

Research Interests

  • Ice crystal icing
  • Volcanic ash ingestion

Current Projects

Development of a three dimensional ice crystal icing measurement system.

A novel optical measurement technique utilising stereo vision and laser illuminations is being developed for transient, three dimensional measurements of ice crystal icing.


Development of the ice crystal icing numerical prediction code, ICICLE.

Recent work has focussed on numerical efficiency improvements of the code, and the implementation of coupling between the predicted accretion profile and the continuous phase CFD solution.
