Numerical Simulation of Interaction of Short Pulse Lasers with Plasma
Author: Amol Holkundkar
Publisher: LAP Lambert Academic Publishing
ISBN: 9783845419381
Category :
Languages : en
Pages : 160
Book Description
Development of high power lasers opened a new era of scientific innovations. Now it is possible to study the matter properties under extreme conditions applicable to large number of potential applications. The field of laser-plasma interaction is very vast and wealthy in content. In this thesis we present three basic aspects related to the subject.We have developed a new model for laser interaction with solid targets which is applicable for the laser pulse duration ranging from femtoseconds to picoseconds. The benchmarking of the model is done by testing various special cases. The absorption model is coupled with one dimension radiation hydrodynamics, opacity and equation of state data in order to simulate various experiments. The interaction of laser with atomic cluster is also investigated in this monograph. A new hydrodynamic model for laser cluster interaction is presented. Our model takes into account the radial non-uniformity of the expanding cluster under the influence of incident laser. Finally the laser induced ion acceleration is also studied using one dimensional particle-in-cell code.

Energy Transfer and Dissipation in Plasma Turbulence
Author: Yan Yang
Publisher: Springer
ISBN: 9811381496
Category : Science
Languages : en
Pages : 134
Book Description
This book revisits the long-standing puzzle of cross-scale energy transfer and dissipation in plasma turbulence and introduces new perspectives based on both magnetohydrodynamic (MHD) and Vlasov models. The classical energy cascade scenario is key in explaining the heating of corona and solar wind. By employing a high-resolution hybrid (compact finite difference & WENO) scheme, the book studies the features of compressible MHD cascade in detail, for example, in order to approximate a real plasma cascade as “Kolmogorov-like” and to understand features that go beyond the usual simplified theories based on incompressible models. When approaching kinetic scales where plasma effects must be considered, it uses an elementary analysis of the Vlasov–Maxwell equations to help identify the channels through which energy transfer must be dissipated. In addition, it shows that the pressure–strain interaction is of great significance in producing internal energy. This analysis, in contrast to many other recent studies, does not make assumptions about wave-modes, instability or other specific mechanisms responsible for the dynamics – the results are direct consequences of the Vlasov–Maxwell system of equations. This is an important step toward understanding dissipation in turbulent collisionless plasma in space and astrophysics.

Pages : 49
Book Description
This work uses direct numerical simulation to study the thermal effect of a region of plasma on quiescent air. The simulations solve the compressible ideal gas Navier-Stokes equations using Fourier spectral methods. A shock capturing scheme is incorporated to account for the strong shock waves. Also, a logarithmic formulation for the continuity equation is developed to handle low densities at the core of the plasma.
