Journal ArticleDOI
On the identification of a vortex
Jinhee Jeong,Fazle Hussain +1 more
TL;DR: In this article, the authors propose a definition of vortex in an incompressible flow in terms of the eigenvalues of the symmetric tensor, which captures the pressure minimum in a plane perpendicular to the vortex axis at high Reynolds numbers, and also accurately defines vortex cores at low Reynolds numbers.
Journal ArticleDOI
Coherent structure generation in near-wall turbulence
Wade Schoppa,Fazle Hussain +1 more
TL;DR: In this paper, the authors present a new mechanism for generation of near-wall streamwise vortices, which dominate turbulence phenomena in boundary layers, using linear perturbation analysis and direct numerical simulations of turbulent channel flow.
Journal ArticleDOI
Coherent structures near the wall in a turbulent channel flow
TL;DR: In this paper, Jeong et al. used a conditional sampling scheme to extract the entire extent of dominant vortical structures near the wall in a numerically simulated turbulent channel flow.
Journal ArticleDOI
Elliptic jets. I - Characteristics of unexcited and excited jets
Fazle Hussain,Hyder S. Husain +1 more
TL;DR: Experimental studies of incompressible elliptic jets of different aspect ratios and initial conditions are summarized along with the effects of excitations at selected frequencies and amplitudes in this paper, where the experimental facilities and procedures are described and jet spread and decay are discussed.
Journal ArticleDOI
Propagation velocity of perturbations in turbulent channel flow
John Kim,Fazle Hussain +1 more
TL;DR: In this article, a database obtained from direct numerical simulation of a turbulent channel flow is analyzed to extract the streamwise component of the propagation velocity V of velocity, vorticity, and pressure fluctuations from their space-time correlations.
