The numerical integration of the differential equations describing chemical kinetics
consumes the majority of computational time in combustion simulations that involve direct …

Computational prediction of thermoacoustic instabilities arising in gas turbine and aero-
engine combustors still remains a challenge especially if fuel is injected in a liquid spray …

Identifying combustion regimes in terms of premixed and non-premixed characteristics is an
important task for understanding combustion phenomena and the structure of flames. A …

The paper examines the combined effects of several interacting thermo-acoustic and
hydrodynamic instability mechanisms that are known to influence self-excited combustion …

This work proposes a chemical mechanism tabulation method using artificial neural
