Breaking the Kolmogorov Barrier with Nonlinear Model Reduction
Benjamin Peherstorfer
Source abstract
This article describes the Kolmogorov barrier of linear model reduction and then outlines how nonlinear methods can overcome the barrier. A numerical example of simulating combustion instabilities in a single-injector element of a rocket engine demonstrates adaptive empirical interpolation as one example of a nonlinear model reduction method.
