Current Project

Large Eddy Simulation of High frequency thermo acoustic instability
Start of Project: Feb. 2015


The work aims to identify the underlying causes and physical mechanisms of HF combustion dynamics as observed in industrial gas turbine combustors. Forced response Simulation in generic combustion chamber as well as self-excited simulation in technical combustion chamber will be carried out. For this purpose, a 3D CFD open source software coupled with a LES in-house code for turbulent combustion will be used.  The knowledge on influence parameters and feedback mechanism shall be used to derive a predictive model  on high-frequency instabilities.
