PhD project:

Title: Full gas dynamics and exergetic analysis of PGC cycles with rotating detonations. (ESR 15)

Short description: The PhD project focuses on the Rotating Detonation Engine (RDE). The first task is to successfully integrate the turbine to the rotating detonation combustor (RDC) outlet with 1D unsteady Euler model. Then, develop the reduced order model for the RDC. Finally, to have the whole cycle simulation of RDE, that is, integrating the compressor, RDC, and turbine. 

Supervisor:  Prof. Panagiotis Stathopoulos

Mentor: xxxxx xxxxx

Planned secondments: 

  • CERFACS (M18 – M20) – Aim to develop the reduced order model for the rotating detonation combustor that will be integrated to the whole model.
  • UNIGE (M27 – M29) – To broaden the understanding on transient and time-dependent gas turbine simulations and assist the collegeaus there for the development of their own reduced order model for rotating detonation combustor.


  • Born in Chennai, India
  • Bachelors in AERONAUTICAL Engineering from Madras Institute of Technology, India (07/2014–04/2018).
  • Master in AERONAUTIQUE et ESPACE with specialization in Energetics and Propulsion from ISAE-ENSMA, France (09/2018 – 01/2021).
