Essentially it is a thermoacoustic engine that provides pulsating flow down a tube to provide cooling. Similar to a reverse stirling cycle without the moving parts

Oscillating pressures inside a tube closed at one end will cause the gas to be heated at the closed end during compression and cooled at the other end during expansion. Basic refrigeration cycle

Okay thanks. But I was referring to self excited oscillations produced from therm-acoutics coupling in gas turbine combustor. Which is a problem of concern nowadays in the disgn of Low Nox gas turbine combustor.

Clients of us have been working with RADIOSS-CFD to produce some thermal acoustic flow in a gaz turbine.
I can provide the published paper by e-mail if needed. 'Numerical Analysis of acoustic-flow interaction in a gas turbine combustion chamber' Dariusz Nowak ALSTOM Dimitri Nicolopoulos dimitri@mcube.fr www.mcube.fr |
