Abstract: A threedimensional finite element code is used for the eigenvalue analysis of the thermoacoustic combustion instabilities modeled through the Helmholtz equation. A full annular combustion chamber, equipped with several ...

Abstract: Most annular combustors feature a discrete rotational symmetry so that the full configuration can be obtained by copying one burnerflame segment a certain number of times around the circumference. A thermoacoustic model ...

Abstract: This paper presents a Reynolds averaged Navier Stokes turbulent combustion model for CH4/H2/air mixtures which includes the effect of heat losses and flame stretch. This approach extends a previous model concept designed ...
