Bifurcation Dodge: Avoidance of a Thermoacoustic Instability under Transient Operation

, 2018
Varying one of the governing parameters of a dynamical system may lead to a critical transition, where the new stable state is undesirable. In some cases, there is only a limited range of the bifurcation parameter that corresponds to that unwanted ...
