Thermo-acoustics
Somebody working in the field of thermo-acoustics? Pr

Re: Thermo-acoustics
we have worked on pulse tubes?

Re: Thermo-acoustics
Can you elaborate on that pulse tubes.? Pr
|
Re: Thermo-acoustics
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
|
Re: Thermo-acoustics
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

Re: Thermo-acoustics
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.

Re: Thermo-acoustics
Does this mean that
Pr = Pratap ? |
Re: Thermo-acoustics
Yeah

Re: Thermo-acoustics
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 |
