Spatial-Temporal Instability of an Inviscid Shear Layer

Spatial Stability of Inviscid Homogeneous Parallel Shear Flows

In this paper the spatial instability of Kuo’s problem has been discussed. Some stability results have been established for 0 > r k . The spectrum of eigen values has been obtained.

Shear layer instability at low reynolds numbers

Parallel implicit DNS of temporally-evolving turbulent shear layer instability

In this study, temporally-evolving incompressible and compressible Turbulent Shear Layer (TSL) instability problem is solved using an all-speed (allMach), implicit, non-dissipative and kinetic energy conserving algorithm. An in-house, fully parallel, finite-volume Direct Numerical Simulation (DNS) solver was developed using PETSc. Convergence characteristics at low-Mach numbers were also improv...

The shear-layer instability of a circular cylinder wake

A reinterpretation is made of previously published data concerning the frequency of the instability waves in the separated shear layer from a circular cylinder for Reynolds numbers in the range 103–105. An accurate fit to the observed variation can be achieved using a piecewise fit based on theoretical and empirical arguments. A logical conclusion is that the ratio of the frequency of the insta...
