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…
Effects of gravity on lean hydrogen/air flame instability: From linear scaling law to nonlinear morphology evolution
Qizhe Wen, Yan Wang, Linlin Yang +4
The instability characteristics of lean hydrogen/air flames have attracted considerable research attention, yet the effect of gravity remains insufficiently understood. In this stu…
Eigenvalue-based Linear Stability Analysis of Intrinsic Instabilities in Laminar Flames
Thomas Ludwig Kaiser, Peter Munch, Sandra May +1
Intrinsic instabilities of laminar premixed flames play an important role in the dynamics of hydrogen combustion and in the development of predictive models for reacting flows. How…
A convolutional autoencoder and neural ODE framework for surrogate modeling of transient counterflow flames
Mert Yakup Baykan, Weitao Liu, Thorsten Zirwes +3
A novel convolutional autoencoder neural ODE (CAE-NODE) framework is proposed for a reduced-order model (ROM) of transient 2D counterflow flames, as an extension of AE-NODE methods…
