The quark-gluon plasma produced in heavy-ion collisions is anisotropic throughout its evolution. This anisotropy changes the physics of jet-medium interaction, making it dependent on momentum direction jet. In this paper we analyze transverse broadening a jet parton interacting with soft gluons an plasma. Our analysis equally applies to quasiparticles kinetic theory. We subtract contribution fr...

The first laboratory astrophysics experiments to produce a radiatively cooled plasma jet with dynamically significant angular momentum are discussed. A new configuration of wire array z pinch, the twisted conical wire array, is used to produce convergent plasma flows each rotating about the central axis. Collision of the flows produces a standing shock and jet that each have supersonic azimutha...

We argue that the narrow line regions of Seyfert galaxies are powered by the transport of energy and momentum by the radio-emitting jets. This implies that the ratio of the radio power to jet energy flux is much smaller than is usually assumed for radio galaxies. This can be partially attributed to the smaller ages (∼ 106 yrs) of Seyferts compared to radio galaxies but one also requires that ei...

Abstract Erosion of an aluminium oxide surface as well a formation coating on substrate, comparable with erosion and induced by plasma electrolytic oxidation (PEO), can be caused at atmospheric pressure conditions DBD-like (Dielectric Barrier Discharge) jet. Obtained experimental results conform previously assumed similarity the mechanisms jet PEO microdischarges. The mechanism predominantly in...

Fluorescence excitation spectra for transition à Au – X̃ Ag of trans-glyoxal in a supersonic jet were recorded with laser excitation in a wavelength region near 395 nm. With resolution 0.04 cm, most lines in these spectra are resolved and are assigned rotationally; of six bands assigned, three have c-type rotational structure, and another three have types a/b hybrid, a and b . Fluorescence decay...

The operational characteristics of the experimental direct current plasma torch with water vapor stabilization of the arc discharge and diagnostics of generated plasma jet at the nozzle exhaust of the torch were studied in this research. The operation parameters of the torch are presented in terms of generalized thermal and electrical characteristics, which were compared with equations for stea...

The study of core noise from turbofan engines has becomemore important as noise from other sources such as the fan and jet were reduced. A multiple-microphone and acoustic-source modeling method to separate correlated and uncorrelated sources is discussed. The autoand cross spectra in the frequency range below 1000Hz are fitted with a noise propagation model based on a source couplet consisting...
