On the Speed of Astrophysical Jets
نویسنده
چکیده
The evolution of the speed of astrophysical jets relative to the ambient medium is investigated using a simple model. We assume that a jet clump is under the influence of the relativistic tidal force of the central source as well as the plasma force due to the electromagnetic field of the ambient medium. The resulting equation of motion predicts that in time the speed of the clump tends to the ambient electrical drift speed. PACS numbers: 04.20.Cv, 98.58.Fd;

Designing and Manufacturing the Multiple Jets Simulator and Experimental Investigation of the Multiple Jets in Crossflow
Designing and manufacturing the multiple jets simulator and experimental investigation of the multiple jets in crossflow at low velocity ratios have been studied Together with design and build a low-speed wind tunnel. A specific rake is used to determine the flow field pressure and changes in static pressure measured by pressure taps in the near field of the jets. There are generally three regi...

متن کاملMiniconference on astrophysical jets
This miniconference brought together observers of astrophysical jets, analytic and numerical modelers of both astrophysical jets and spheromaks, and laboratory experimentalists. The purpose of the miniconference was to encourage interaction between these diverse groups and also expose the plasma physics community to the interesting plasma issues associated with astrophysical jets. The miniconfe...
متن کامل/ 06 07 35 0 v 1 1 5 Ju l 2 00 6 Simple scaling laws for astrophysical jets
The idea of a unified model for all astrophysical jets has been considered for quite some time. We present here a few scaling laws relevant to all type of astrophysical jets, analogous to those of Sams et al. (1996) which are widely used for astrophysical black holes. We use Buckingham's Π theorem of dimensional analysis to obtain a family of dimensional relations among the physical quantities ...
متن کاملNumerical Simulation of High Mach Number Astrophysical Jets with Radiative Cooling
Computational fluid dynamics simulations using the WENO-LF method are applied to high Mach number nonrelativistic astrophysical jets, including the effects of radiative cooling. Our numerical methods have allowed us to simulate astrophysical jets at much higher Mach numbers than have been attained (Mach 20) in the literature. Our simulations of the HH 1-2 astrophysical jets are at Mach 80. Simu...
