Assessment of combustion noise in a premixed swirled combustor via Large-eddy<br />
simulation<br />
Silva, C., Leyko, M., Nicoud, F., and Moreau, S.<br />
Computers & Fluids, accepted (2010)<br />
This article shows the computation of noise in a premixed swirled combustor by both direct<br />
and hybrid approaches. The direct approach is performed by a LES solver (AVBP) while the<br />
hybrid approach is carried out by an acoustic solver (AVSP-f) <strong>de</strong>veloped during this thesis.<br />
Results coming from both approaches are compared and discussed.<br />
Extracting the acoustic pressure field from Large-eddy simulation of confined<br />
reactive flows<br />
Silva, C., Nicoud, F., and Moreau, S.<br />
in 16th AIAA/CEAS Aeroacoustics. Stockholm, Swe<strong>de</strong>n (2010)<br />
Based on the previous work, it has been realized that it is not appropriate to directly compare<br />
the pressure fluctuations coming from LES and those coming from the acoustic solver<br />
when computing noise in a confined domain: hydrodynamic pressure fluctuations must be<br />
removed from the pressure field so that a proper acoustic field is obtained. A method to extract<br />
the acoustic field from the entire pressure field given by LES is proposed.<br />
