Flow Instabilities in Flute-like Instruments
… fields including fluid dynamics, physics, and aero-acoustics. In this study, an effort has been made to investigate more about the flow of air in flutes using 2D Direct Numerical Simulation. An analysis of the response of the jet of air by varying the jet width, profile, offset, and Reynolds …

DGM-FD: A Finite Difference Scheme Based on the Discontinuous Galerkin Method
… in many areas of study such as computational aero-acoustics (CAA). While dissipation and dispersion errors influence the accuracy of a method, efficiency can be assessed by convergence rates and effective adaptability to different mesh structures. Finite difference and finite element methods …

Direct numerical investigation and reduced-order modeling of 3-D honeycomb acoustic liners
Single degree-of-freedom conventional acoustic liners are widely installed in jet engines to reduce internal engine noise. They work by converting acoustic energy into vorticity-bound fluctuations. Despite being widely used, effective design-stage models of acoustic liners placed in high sound …
