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…
GPU Benchmark through QPE Emulator with cuQuantum for Practical Quantum Applications
Takaki Akiba, Youhi Morii
The quantum algorithm of Quantum Phase Estimation (QPE) was implemented to make the maximum use of GPU emulation with cuQuantum and CUDA Toolkit by NVIDIA. The input and output wer…
Weak Detonations Revisited: Uncovering Its General Nature Using Autoignitive Reaction Wave Concept
Youhi Morii, Kaoru Maruta
Weak detonations have remained experimentally elusive since their theoretical prediction, with previous realization attempts requiring either pathological detonations or Zeldovich…
General concept for autoignitive reaction wave covering from subsonic to supersonic regimes
Youhi Morii, Kaoru Maruta
We consider a one-dimensional (1D) autoignitive reaction wave in reactive flow system comprising unburned premixed gas entering from the inlet boundary and burned gas exiting from…
What connects ignition and deflagration? -- On explosive transition of deflagration
Youhi Morii, Kaoru Maruta
The general relation between ignition and deflagration analyses was studied theoretically and computationally. Simple analysis showed that the temporal evolutions of normalized fue…
Carleman linearization approach for chemical kinetics integration toward quantum computation
Takaki Akiba, Youhi Morii, Kaoru Maruta
The Harrow, Hassidim, Lloyd (HHL) algorithm is a quantum algorithm expected to accelerate solving large-scale linear ordinary differential equations (ODEs). To apply the HHL to non…
Optimization of One-parameter Family of Integration Formulae for Solving Stiff Chemical-kinetic ODEs
Youhi Morii, Eiji Shima
A fast and robust Jacobian-free time-integration method - called Minimum-error Adaptation of a Chemical-Kinetic ODE Solver (MACKS) - for solving stiff ODEs pertaining to chemical-k…
