Approximation of slow and fast dynamics in multiscale dynamical systems by the linearized Relaxation Redistribution Method
Eliodoro Chiavazzo
In this paper, we introduce a fictitious dynamics for describing the only fast relaxation of a stiff ordinary differential equation (ODE) system towards a stable low-dimensional in…
Fast computation of multi-scale combustion systems
Eliodoro Chiavazzo, Filippo Visconti, Pietro Asinari
In the present work, we illustrate the process of constructing a simplified model for complex multi-scale combustion systems. To this end, reduced models of homogeneous ideal gas m…
Adaptive simplification of complex multiscale systems
Eliodoro Chiavazzo, Ilya Karlin
A fully adaptive methodology is developed for reducing the complexity of large dissipative systems. This represents a significant step towards extracting essential physical knowled…
Method of invariant grid for model reduction of hydrogen combustion
E. Chiavazzo, I. V. Karlin, C. E. Frouzakis +1
The Method of Invariant Grid (MIG) is a model reduction technique based on the concept of slow invariant manifold (SIM), which approximates the SIM by a set of nodes in the concent…
Quasi Equilibrium Grid Algorithm: geometric construction for model reduction
E. Chiavazzo, I. V. Karlin
The Method of Invariant Grid (MIG) is an iterative procedure for model reduction in chemical kinetics which is based on the notion of Slow Invariant Manifold (SIM) [1-4]. Important…
