New publication of Merk et al. in CNF on thermoacoustic jump conditions

22.01.2025

Our paper "A Jacobian-based framework for the derivation of comprehensive thermoacoustic jump conditions" by Moritz Merk et al. has appeared in the journal Combustion and Flame. This study proposes a novel framework for developing jump conditions for compact elements of thermoacoustic network models. Unlike the established approach of deriving case-specific jump conditions "by hand", our Jacobian-based method generates jump conditions valid for a wide range of application cases with a modularity that eases implementation and the possibility of straightforward a posteriori customization for specific application cases.

For the first time, jump conditions for acoustic, entropic and compositional
perturbations across a lean premixed flame that allow for arbitrary Mach numbers, realistic gas properties as well as flame movement are developed.
