Magnetized jets in laboratory astrophysics

Abstract

The main goal of this work is the numerical investigation of the plasma dynamic evolution of Z-pinch and X-pinch devises. A more thorough investigation of the jet formation mechanisms and dynamic evolution of a two-wire tungsten X-pinch formation along with experimental validation is presented. Additionally a possible correlation to astrophysical jets of YSO and HH objects is discussed. Specifically this study contributes to the estimation of the scalability factors and all the relevant numbers and parameters for a low current X-pinch tungsten plasma configuration. In order to achieve robust, flexible and realistic computational simulation models, a variety of different numerical and physical schemes is needed. An extra study for this dissertation, is the synthesizing process of extracting physical formulas for all the dissipative terms for all density and temperature regimes. The synthesis of different physical formulas for piece-wise functions or correction factors to already known f ...
