Quasi-DNS with chemical kinetics for near blow-out dynamics of a single multi-injection burner element for future gas turbine applications
Kazuki Abe, Youhi Morii, Kaoru Maruta
Gas turbine combustors increasingly operate close to lean blow-out (LBO) limits, where small changes in fuel-air mixing or flow structure can destabilize the flame and alter near-b…

Duplicate-Aware Shift-and-Lift Carleman Linearization:Structure, Complexity, and Comparative Evaluation
Takaki Akiba, Youhi Morii
The primary objective of this study is to remove duplicated monomial contributions that proliferate in Carleman linearization as state dimension and truncation order increase. To d…

Effects of Soret diffusion on the intrinsic instability of premixed hydrogen/air flames
Qizhe Wen, Yan Wang, Linlin Yang +4
Hydrogen flames exhibit multiple intrinsic instabilities. The low molar masses of H and H2 lead to significant Soret diffusion near the flame front; however, its influence on hydro…
