Journal ArticleDOI
Compact finite difference schemes with spectral-like resolution
TL;DR: In this article, the authors present finite-difference schemes for the evaluation of first-order, second-order and higher-order derivatives yield improved representation of a range of scales and may be used on nonuniform meshes.
Journal ArticleDOI
Computational aeroacoustics: progress on nonlinear problems of sound generation
Tim Colonius,Sanjiva K. Lele +1 more
TL;DR: A hierarchy of computational approaches that range from semi-empirical schemes that estimate the noise sources using mean-flow and turbulence statistics, to high-fidelity unsteady flow simulations that resolve the sound generation process by direct application of the fundamental conservation principles is discussed in this paper.
Journal ArticleDOI
Motion of particles with inertia in a compressible free shear layer
Mo Samimy,Sanjiva K. Lele +1 more
TL;DR: In this article, the effects of the inertia of a particle on its flow-tracking accuracy and particle dispersion were studied using direct numerical simulations of 2D compressible free shear layers in convective Mach number (Mc) range of 0.2 to 0.6.
Journal ArticleDOI
Computational prediction of flow-generated sound
TL;DR: A critical review of computational techniques for flow-noise prediction and the underlying theories, in which the turbulent noise source field is computed and/or modeled separately from the far-field calculation, is provided.
