ESR 3: Nilam Tathawadekar (GE)

My current research focuses on machine learning in the area of combustion instabilities. The basic idea is to improve sub-models of premixed combustor using deep learning techniques. Since September 2018, I am an Early Stage Researcher in General Electric (GE) Aviation Digital, Munich.

I am alumni of Indian Institute of Science, Bangalore. Here is the link to my work on eRetail demand forecasting using deep neural networks.

ESR 5: Sagar Kulkarni (TUM)

I am Sagar Kulkarni, a Marie Curie Early Stage Researcher at TU Munich. I am from India and have an M.Sc., in Mechanical Engineering from TU Delft, Netherlands. For my Master thesis, I carried out CFD analysis of a Micro Gas Turbine Flameless Oxidation spray burner for range extension application for electric vehicles at the Institute of Combustion Technology, DLR, Cologne and TU Delft.

As an ESR my work packages include LES of spray combustion for low order modelling of the dynamics and Uncertainty Quantification. In detail, I will be carrying out LES of spray flame in presence of acoustics in AVBP to determine the Flame Transfer Function (FTF) of the system. Then use the System Identification procedure to quantify the uncertainty of the FTF with respect to simulation parameters such as length of the time series and number of droplet parcels modelled.

As a result, I look at Flame Impulse Response (IR) and transfer function of the liquid fuel combustion, analyse the contribution of various physical processes (eg. atomization, evaporation) to the overall flame response in terms of frequency response functions.

I look forward to the cooperation from other partners (academic and industrial) towards the project to really deliver the goals and make a step towards mitigating instabilities from aero engines!!

ESR 9: Alireza Javareshkian (TUM)

Starting from the middle of March, 

Alireza Javareshkian 

started his project at the institute. The aim of this project which is funded by EU project-MAGISTER (H2020-MSCA-ITN-2017), is further investigation of acoustic behavior of combustor liners with dilution holes in aero GT engines. Characterization and modelling of acoustically absorbing liners would be performed through the course of this project, aiming acoustic characterization of perforated medium, measurement of damping rates of a combustion system with and without perforated medium and benchmark of measured and predicted (1D-network, LNSE) results.

Research Topic: Investigation of the use of Lattice-Boltzmann method applied to multiphasic flows:

The numerical study of injection is a critical point if we consider the behaviour of a flame as both the flame and the injection responses to thermo-acoustic waves are coupled. Consequently, the study of the physic of injection is sensitive if we want to determine the physic of a combustion chamber.

A lot of current numerical simulation of multiphasic flows relies on front tracking methods, that are computationally expensive and not always efficient to catch breaking phenomena and particularly primary atomization. On another hand, Lattice-Boltzmann (LB) methods have recently shown a great degree of maturity and could be able to simulate multiphasic problems with high-density ratio in a close future. The first part of this work consists in investigating the potential of those methods on our applications. Afterwards, we will consider the use of machine learning in determining automatically the tunable parameters that are inherent to LB methods.
