Kelvin-Helmholtz Instability in Magnetized Plasma
… perpendicular to the plasma velocity forms. The magnetized Kelvin-Helmholtz instability was further investigated using intrinsically magnetized pulsed power-generated plasma flows. The flows were produced by using quasi-planar arrays of wires inclined such that their connections were closer at …

Instabilities and transport in magnetized plasmas
In a magnetized plasma, naturally occurring pressure anisotropies facilitate in- stabilities that are expected to modify the transport properties of the system. In this thesis we examine two such instabilities and, where appropriate, their effects on transport. First we consider the collisional …

Alfven-Rossby Waves in Rotating Magnetized Stars
Using Hamiltonian methodology, we clarified a common misunderstanding of the origin of kinematic drifts. We studied the weakly nonlinear interactions between linear Alfven-Rossby waves. We used a spherical harmonic representation in which the fully nonlinear MHD equations are replaced by an …

Magneto-thermal Instability in Dilute Magnetized Plasmas
In dilute, magnetised plasmas exchanges of heat across magnetic field lines are strongly suppressed, as charged particles rapidly gyrate around magnetic field lines but only infrequently scatter due to Coulomb collisions. The anisotropic heat conduction, in the presence of a large-scale temperature …

Disk Accretion to Rotating Magnetized Stars: Magnetohydrodynamic Simulations
The star-disk interaction between a rotating magnetized star and a surrounding accretion disk is a fundamental process in astrophysics, and is usually difficult to investigate due to the complicated magnetohydrodynamic structures. The aim of this work is for understanding the accretion …

Magnetized models for the formation of the moon
… using numerical simulations. To evolve a magnetized, Moon-forming giant impact scenario, we must integrate the equations of magnetohydrodynamics subject to a planetary equation of state with self-gravity. Herein, we have implemented various extensions to the Athena++ framework (Stone et …

Kinetic electron phenomena in dense magnetized plasma wakes
Flow past an obstacle by dense magnetized plasma, having both Debye-length and gyroradii smaller than the obstacle, is explored using particle-in-cell (PIC) simulations. These simulations are relevant to a wide range of physical settings, ranging from the moon in the (supersonic) solar wind to Mach …

A geodesic finite-difference time-domain model of magnetized plasma
… been developed that treats the ionosphere as a magnetized cold plasma. This opens the door to modeling electromagnetic phenomena at higher frequencies and higher altitudes by accommodating more physics. Further, a geodesic (hexagonal-pentagonal) FDTD model that is more efficient, is easier to …

Discontinuous Galerkin modeling of plasma turbulence in a simple magnetized torus
Plasma turbulence in the Texas Helimak, a simple magnetized torus (SMT) experiment, has been simulated with fluid and gyrokinetic continuum models that employ the discontinuous Galerkin (DG) computational method. SMTs are physical approximations of a sheared cylinder and, with simple magnetic …

Analysis and Modeling of Magnetized Microswimmers: Effects of Geometry and Magnetic Properties
In recent years, much effort has been placed on development of microscale devices capable of propulsion in fluidic environments. These devices have numerous possible applications in biomedicine, microfabrication and sensing. One type of these devices that has drawn much attention among researchers …
