Implicit Tensor-Train Cross Integration of High-Dimensional Nonlinear PDEs via Fiber-Dependency Elimination
Behzad Ghahremani, Hessam Babaee
Tensor-train (TT) representations have emerged as an effective framework for mitigating the curse of dimensionality in the numerical solution of high-dimensional tensor differentia…
Kinetic-Mamba: Mamba-Assisted Predictions of Stiff Chemical Kinetics
Additi Pandey, Liang Wei, Hessam Babaee +1
Accurate chemical kinetics modeling is essential for combustion simulations, as it governs the evolution of complex reaction pathways and thermochemical states. In this work, we in…
AMORE: Adaptive Multi-Output Operator Network for Stiff Chemical Kinetics
Kamaljyoti Nath, Additi Pandey, Bryan T. Susi +2
Time integration of stiff systems is a primary source of computational cost in combustion, hypersonics, and other reactive transport systems. This stiffness can introduce time scal…
Skeletal Reaction Models for Gasoline Surrogate Combustion
Yinmin Liu, Hessam Babaee, Peyman Givi +2
Skeletal reaction models are derived for a four-component gasoline surrogate model via an instantaneous local sensitivity analysis technique. The sensitivities of the species mass…
On-the-fly Reduced-Order Modeling of the Filter Density Function with Time-Dependent Subspaces
Aidyn Aitzhan, Peyman Givi, Hessam Babaee
A dynamical low-rank approximation is developed for reduced-order modeling (ROM) of the filtered density function (FDF) transport equation, which is utilized for large eddy simulat…
Optimally time-dependent modes of vortex gust-airfoil interactions
Yonghong Zhong, Alireza Amiri-Margavi, Hessam Babaee +1
We find the optimally time-dependent (OTD) orthogonal modes about a time-varying flow generated by a strong gust vortex impacting a NACA 0012 airfoil. This OTD analysis reveals the…
