Gas turbine combustion chambers contain numerous small-scale features that help to dampen acoustic waves and alter the acoustic mode shapes. This damping helps to alleviate problems such as thermoacoustic instabilities. During computational fluid dynamics simulations (CFD) of combustion chambers, these small-scale features are often neglected as the corresponding increase in the mesh cell count augments significantly the cost of simulation while the small physical size of these cells can…

TLDR
The implementation of various types of turbulence modeling in a FOAM computational-fluid-dynamics code is discussed, and calculations performed on a standard test case, that of flow around a square prism, are presented.

Thermoacoustic stabilization of a longitudinal combustor using adjoint methods

TLDR
A low-order thermoacoustic network model is constructed that contains the most influential physical mechanisms of a therMOacoustic system and is applied to a laboratory-scale longitudinal combustor that has been found to be thermoACoustically unstable in experiments.
