Data-driven stability analysis in a multi-element supercritical Liquid Oxygen-methane combustor
Arijit Bhattacharya, Abhishek Sharma, Ashoke De
Thermoacoustic instability (TAI) is a pressing problem in rocket combustors. TAI can cause significant damage to a combustor, resulting in mission failure. Therefore, stability ana…
Impact of Fuel Injection Temperature Dynamics on the Stability of Liquid Oxygen-Methane Supercritical Combustion
Abhishek Sharma, Ashoke De, S. Sunil Kumar
A crucial factor in the stability of high-pressure rocket-scale combustors is the temperature at which fuel is injected. This study investigates its effect on the stability of supe…
Investigation of injector-coupled combustion dynamics in a methane-oxygen combustor using large eddy simulation and dynamic mode decomposition
Abhishek Sharma, Ashoke De, Sunil Kumar
This paper uses a reactive flow large eddy simulation (LES) and decomposition techniques to study combustion instabilities in a methane-oxygen combustor. This work examines two cas…
Numerical Investigation of Supercritical Combustion Dynamics in a Multi-Element LOx-Methane Combustor Using Flamelet-Generated Manifold Approach
Abhishek Sharma, Ashoke De, S. Sunil Kumar
The article investigates liquid oxygen (LOx)-methane supercritical combustion dynamics in a multi-element rocket scale combustor using large eddy simulation (LES). A complex framew…
Drop size characteristics of sprays emanating from circular and non-circular orifices in the atomization regime
K. R. Rajesh, V. Kulkarni, S. Vankeswaram +2
Traditionally, circular orifices have been used for generating aerosols, however in recent times non-circular orifices are being considered due to their superior atomization and mi…
Numerical Investigation of Coaxial GCH4/LOx Combustion at Supercritical Pressures
Sindhuja Priyadarshini, Malay K Das, Ashoke De +1
This article aims to numerically investigate the combustion phenomenon of coaxial gaseous CH4 LOx at supercritical pressures. The choice of turbulence model, real gas model, and ch…
