A simple analytical model of magnetic jets

چکیده
ABSTRACT We propose a simple analytical jet model of magnetic jets, in which radially averaged profiles main physical quantities are obtained based on conservation laws and some results published general relativistic magnetohydrodynamic simulations. take into account conversion the energy flux to bulk acceleration jets formed around rotating black holes assuming mass continuity equation constant power, leads Bernoulli equation. For assumed Lorentz factor radius, this gives us profile toroidal field component along jet. then consider case where poloidal is connected hole surrounded by an accretion disc. Our formalism recovers standard formula for power extracted from hole. find that strength dominates over one comoving frame up large distances, means should be more stable current-driven kink modes. The resulting can used calculate synchrotron emission.

A simple Analytical model for solidification cooling rate based on the local heat flux density
A new simple analytical model for prediction of cooling rate in the solidification process based on the local heat flux density extracted during solidification is introduced. In the modeling procedure, a solidifying control volume is considered in the mushy zone in which a heat balance equation is used to derive the present model. As the local heat flux density is a measurable parameter, the pr...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
A simple magnetic refrigerator evaluation model
The simple evaluation model utilizing the selective parameters for the preliminary analysis for magnetic refrigerator (MR) development is proposed in this paper. The magnetocaloric effect and the related magnetic field applied for MR are also discussed. The model and system analysis following the algorithm expressions and the material characteristics required for MR are arranged and derived in ...
