This paper presents preliminary velocity and scalar measurements of low swirl intensity jets in air. Swirling jets were generated using a micro-injector swirl generator. Velocity fields of the jets were obtained using Multi-grid Cross Correlation Digital Particle Image Velocimetry. Initial flow visualizations were performed using planar laser induced fluorescence with acetone as tracer species.

The jets of GRS 1915+105 carry a considerable energy away from the central source into the ISM. The similarity of the jets of this source and jets in radio galaxies or radio-loud quasars suggests that we should detect large-scale, synchrotron emitting radio structures surrounding GRS 1915+105. However, these large structures have not been found. We show that by adapting a model for the radio lo...

Turbulent fluids are frequently observed to spontaneously self-organize into large spatial-scale jets; geophysical examples of this phenomenon include the Jovian banded winds and the earth’s polar-front jet. These relatively steady large-scale jets arise from and are maintained by the smaller spatialand temporalscale turbulence with which they coexist. Frequently these jets are found to be adju...

In forced two-dimensional turbulence on a rotating sphere, it is well known that a multiple zonal-band structure, i.e. a structure with alternating eastward and westward jets, emerges in the course of time development. The multiple zonal-band structure then experiences intermittent mergers and disappearances of zonal jets, and a structure with only a few large-scale zonal jets is realised as an...

The formation and evolution of 3D synthetic jets is examined using direct numerical simulations. The primary focus of the current study is on examining the formation of 3D synthetic jets and the effect of changes in the jet aspect-ratio on the flow produced by the jet. Jets in quiescent and cross-flow cases are investigated. The study compares the vortex dynamics, velocity profiles and the othe...

We discuss the propagation of radiative MHD jets and outflows focusing on outflows driven by magnetocentrifugal rotators. Our goal is to link the properties of the jets with the physics of the sources which produce them. We find that density and magnetic field stratification (with radius) in jets from magnetized rotators leads to new behavior including the development of a dense inner jet core ...

The large missing transverse momentum (MET) plus jets final state topology has great potential for discovery of new physics involving dark matter candidates early in LHC running, if Standard Model backgrounds can be understood. The irreducible background of high transverse momentum (pT) Z bosons, with Z→ νν̄ produced in conjunction with high ET jets, can be estimated from samples of photon plus ...

We calculate the time evolution of the flux, apparent size, and image centroid motion of gamma-ray burst (GRB) jets in the radio, and show that they can be resolved by the VLBA at distances of hundreds of Mpc. We find that GRB 030329 which showed spectroscopic evidence for an associated supernova (SN) Type Ib/c at a distance of ≈ 800 Mpc might just be resolvable by VLBA after several months. Th...

– 2 – We present 3-D numerical hydrodynamical simulations of precessing supersonic heavy jets to explore their evolution, how they differ from straight jets and how well they serve as a model for generating molecular outflows from Young Stellar Objects. The dynamics are studied with a number of high resolution simulations on a Cartesian grid (128x128x128 zones) using a high order finite differe...
