PhD project:

Title: ESR 9: Deflagration-Auto ignition-Detonation transition

Short description: The aim of this project is to 

  • Understand the mechanisms of deflagration/ end-gas auto-ignition/ detonation transitions in the context of CVC and RDC
  • Understand the effect that the specific fuel chemistry has on the deflagration-auto ignition-detonation transition 
  • Formulate strategies for suppressing detonation in CVC and promoting detonations in RDC 

During the course of the project, I will be 

  • Developing regime diagrams based on 1D modeling 
  • Experimentally investigating the deflagration-auto ignition detonation transition
  • Using the experimental results to adapt the 1D model

Background: 

  • I graduated with a Master's Degree in Mechanical engineering in 2017. 
  • I completed my Master's Thesis  in supply-chain management in the private jet industry 
  • I worked for 3 + years as an analyst in London. . During my Job, I ran training courses in basic programming 
  • Due to an interest in sustainability technology, I decided to pursue my PHD
