Spinning modes in orderly jet structure and jet noise
The structural response of a subsonic turbulent jet to controlled forcing has been investigated both theoretically and experimentally. An experimental study has been carried out in which a model jet was subjected to acoustic excitation in the form of circumferential modes of azimuthal wavenumber …

Jet structure and planarity in pi- rho interactions at 147 gev/c
Jet structure and planarity are studied for 1f p reactions at 147 GeV/c using the Proportional Wire Hybrid Spectrometer. The analytical tools used in the investigation include invariants of the momentum tensor for each event and simple models used for comparison with the data. Jet structure is …

Parsec-scale polarization of the jet in quasar 4C 71.07
… of considerable importance in the study of radio jets: longitudinal magnetic fields are thought to help stabilize the jet as it travels outwards from the nucleus and, since magnetic field and jet plasma are frozen together, changes in jet structure are reflected in changes in magnetic field …

Supersymmetric jets from Z boson decay and radiative decays of heavy quarkonium
… of this thesis is devoted to analysis of the jet structure in the final state of the supersymmetric process [equation]. For scalar quark production, as for supersymmetric events in general, the signature which will enable supersymmetry to be discovered in future colliders is missing energy …

Applying SCET to parton showers
… of corrections: hard-scattering corrections and jet-structure corrections. To relate these different effective field theories we make use of an important symmetry of SCET, called reparametrization invariance. In order to systematically study this symmetry, we construct operators that are …

Estimating Cold Nuclear Matter Effects Using Jets In P-Pb Collisions At √snn = 5.02 Tev With The Alice Detector
… of the nuclear modifi- cation factor for jets along with other strongly interacting particles has been observed relative to proton-proton collisions. To unambiguously determine if this suppression is due to the creation of a strongly interacting medium of de-confied partons referred to as …

Numerical Simulation of Injection of Supercritical Ethylene/Methane into Nitrogen
… in the design of hydrocarbon-fueled scramjet engines. The numerical method combines a solution of the compressible Navier-Stokes equations for the supercritical fluid with two different approaches for condensate growth: one based on a homogeneous equilibrium assumption and the other on …

Studies on the ion-droplet mixed regime in colloid thrusters
… fraction of the ion current is emitted from the jet breakup region with considerably lower energies. This energy variety transforms the optical hardware elements into energy filters by taking advantage of the chromatic aberration property of electrostatic lenses. The relatively wide ion energy …

PRESSURE DRIVEN WALL JET FLOW NEAR CHANNEL EXIT AT MODERATE REYNOLDS NUMBER
The wall jet flow driven by a pressure gradient near channel exit at Reynolds Number ranging from the order of 10 to 100, emerging from a two-dimensional channel is examined theoretically in this study. Poiseuille flow conditions are assumed to prevail far upstream from the exit. The problem is …

Relativistic Jets from Compact Binary Mergers as Electromagnetic Counterparts to Gravitational Wave Sources
… the electromagnetic emission from relativistic jets that accompany the merger of binary neutron stars or black hole-neutron star systems. These counterparts provide a probe for the structure and dynamics of these relativistic outflows. Binary neutron star, or neutron star-black hole, mergers are …

Concurrent evaporating spray jets in dilute gas-solid pipe flows
Evaporating spray jets into gas-solids suspensions are encountered in many industrial applications. The rapid evaporation of spray jets has significant effects on the gas-solids mixing near the jet nozzle regions, including non-uniform solids concentration dilution, gas/solids temperature …

Experimental and numerical studies on oil spilling from damaged oil tankers

The fluid-structure interaction of an axisymmetric underexpanded jet flowing across an adjacent compliant surface
… problem of an underexpanded axisymmetric jet flowing across an adjacent parallel surface, in both rigid-surface and compliant-surface configurations. To date, the vast majority of the literature for both the rigid- and compliant-surface cases has been generated by the acoustics community, …
