About me

I am a PhD student within Competence Center for Gas Exchange (CCGEx) and Fluid Physics Laboratory in Department of Engineering Mechanics. I work mainly with Professor Jens H. M. FranssonDr Ramis Örlü and Dr Michael Liverts.

Research Activity

The research is focused in the field of fluid mechanics using various experimental techniques. Current work includes:

  • Investigation on turbocharger turbine performance in steady and pulsating flow
  • Fast-response temperature sensor development and its characterisation
  • Turbulent pipe flow measurements with pulsations
