Coherent structures in an energy-enstrophy theory for axisymmetric flows
The equilibrium statisticalmechanics of a version of an energy-enstrophy theory for the axisymmetric Euler equations is solved exactly in the sense that a configurational integral is calculated in closed form. Under the assumption that the energy and the enstrophy (mean squared azimuthal vorticity) are conserved, a long range version of Kac’s Spherical Model with logarithmic interaction is deri...
متن کاملExperimental Investigations of Supersonic Flow around a Long Axisymmetric Body
A series of supersonic wind tunnel tests on an ogive-cylinder body were performed to investigate the pressure distribution, the boundary layer profiles, and the flow visualization at various angles of attack. All tests were conducted in the trisonic wind tunnel of the Imam Hossein University. The theoretical shock angle at different model positions compared well with those we obtained via Schi...

متن کاملNon-equilibrium scaling laws in axisymmetric turbulent wakes
We present a combined Direct Numerical Simulation and Hot Wire Anemometry study of an axisymmetric turbulent wake. The data lead to a revised theory of axisymmetric turbulent wakes which relies on the mean streamwise momentum and turbulent kinetic energy equations, self-similarity of the mean flow, turbulent kinetic energy, Reynolds shear stress and turbulent dissipation profiles, non-equilibri...
متن کاملVirtual Origin of Incompressible and Supersonic Turbulent Bluff-Body Wakes
TECHNICAL NOTES are short manuscripts describing new developments or important results of a preliminary nature. These Notes cannot exceed six manuscript pages and three figures; a page of text may be substituted for a figure and vice versa. After informal review by the editors, they may be published within a few months of the date of receipt. Style requirements are the same as for regular contr...
