Experiments and modelling of rate-dependent transition delay in a stochastic subcritical bifurcation
- News
- Common Tags
A recent publication of the CAPS laboratory studies the complex dynamics of a lab-scale combustor subject to thermoacoustic instability. This phenomenon is a recurrent issue in constant pressure combustor -such as gas turbines, aeronautical engines or rockets- which can lead to catastrophic failures of the combustion system. This instability can arise suddenly, if the operating condition of the machine is varied.
