TL;DR: In this paper, a 2-D low-order network model based on modal expansions was used to systematically investigate the coupling between different modes of a limit cycle. But the model was not applied to the full 3-D Helmholtz solver.

TL;DR: In this paper, an analytical model based on Green's function method is developed to take the hole length into consideration for short holes, and the importance of capturing the modified vortex noise accurately is shown.

TL;DR: In this paper, the authors investigated the interactions between the pilot and main flames in a novel stratified swirl burner using both experimental and numerical methods, and found that the flame changes from V-shape to M-shape when the main stage is switched from closed to supplying a pure air stream.

TL;DR: In this article, the linear response of an asymmetric planar Bunsen flame under simultaneous axial and transverse perturbations is analyzed using G-equation, and the relation between the flame responses under a 2-dimensional perturbation and separate axial/transverse/separate perturbings is studied to identify a linear 2-D flame response superposition.

TL;DR: In this paper, parallel perforated ceramics with different perforation diameters were installed into the neck of a Helmholtz resonator to improve its acoustic impedance to simultaneously achieve a better acoustic absorption coefficient and a wider absorption bandwidth.
