Dr Oliver Pountney

MEng, PhD

Oliver is a Prize Fellow in Gas Turbine Engineering and a member of the Turbomachinery Research Centre. His research focuses on fluid dynamics and heat transfer in gas turbines.

Profile

Oliver carried out a PhD in modelling and measurement of heat transfer in rotor-stator systems in the Turbomachinery Research Group at Bath. Following his PhD he spent three years in industry working on fluid dynamic and heat transfer related problems for a range of companies, including Airbus and Rolls-Royce.

He returned to the University of Bath in 2015 as a Post-Doctoral Researcher investigating the interaction of mainflow and egress flow paths in a turbine with end-wall contouring.

Oliver was appointed a 50th Anniversary Prize Fellow in August 2016.

Research

Oliver is interested in the experimental modelling of gas turbine fluid dynamic phenomena with a view to scale experimental measurements from rig to engine operating conditions. Specific topics of interest include:

  • Fluid dynamics and heat transfer in turbine secondary air systems
  • Film and internal cooling
  • Interaction between main and egress flow paths in high pressure turbines with end-wall contouring
  • The use of thermochromic liquid crystals and infrared thermography for flow visualisation and heat transfer measurements

His research is conducted with the following key objectives:

  • To further scientific understanding within the gas turbine and wider academic communities through publication
  • Assisting engine designers in their goal of improving gas turbine operating efficiency

Education

  • MEng in Mechanical Engineering, University of Bath
  • PhD in Mechanical Engineering, University of Bath
