Mobile power plants : waste body heat recovery
… of electricity were studied. Thermoelectric, magneto hydrodynamic, and piezo-electric energy conversions at the desired scope were evaluated to understand their role and utility in the efficient conversion of waste body heat. The piezo-electric generator holds the most promise for the …

Well-posedness results for a class of complex flow problems in the high Weissenberg number limit
… is closely related to the incompressible ideal magneto-hydrodynamics (MHD) system. The second result addresses the formulation of a time-dependent elastic boundary layer through scaling analysis. We show the well-posedness of this boundary layer by transforming to Lagrangian coordinates. In …

Extending the dielectric formalism in warm dense matter: collisions, dynamic structure factors, and stopping powers
… evolution with sophisticated radiation- or magneto- hydrodynamics (R/MHD) codes. In turn, the accuracy of R/MHD simulations rely on detailed descriptions of the material properties like transport coefficients, stopping powers, scattering and absorption spectra, and many other quantities in …

Multi-dimensional simulations of bow shocks of massive, high-velocity runaway stars
… runaway (HVR) stars. We use PLUTO, a magneto-hydrodynamics grid code, to simulate these bow shocks, performing hydrodynamic simulations in 2- and 3-dimensions, while including thermal conduction and detailed radiative cooling/heating. Extensive 3D freely expanding stellar wind models …

Theoretical and Experimental Investigation of Magneto Hydrodynamic Propulsion for Ocean Vehicles
The concept of Magneto-Hydrodynamic (MHD) propulsion can be used to implement a propeller-less propulsion system for marine vehicles. The basic principle behind MHD is to use the (Lorentz) force produced by the interaction of electric and magnetic fields to generate thrust on a conducting fluid in …

Magnetized models for the formation of the moon
… linearly in time. Turbulence driven by the magnetorotational instability (MRI) is capable of growing field strengths exponentially in time (Balbus & Hawley, 1998). In this dissertation, we assess the potential role of magnetic fields in the Moon-forming giant impact hypothesis using …

Meshless hydrodynamic simulations of young supernova remnants
… We used the massively parallel, multi-physics magneto-hydrodynamics (MHD) and gravity code, GIZMO, for our simulations. We chose GIZMO for its flexibility in allowing the user to choose different methods to solve the fluid equations, i.e., new Lagrangian Godunovtype schemes, e.g., Meshless …

Characterization of Liquid Metal Free Surface Response to an Electromagnetic Impulse and Implications for Future Nuclear Fusion Devices
Liquid metals (LMs) are compelling candidates for use as plasma facing components (PFCs) in fusion devices to mitigate heat loading, limit damage due to erosion, and possibly breed tritium. When used as electrodes, such as in z-pinch devices, PFCs are subject to large current and magnetic flux …

Modeling the Dynamics of Liquid Metal in Fusion Liquid Walls Using Maxwell-Navier-Stokes Equations
… wall in such fusion devices. The conventional magneto-hydrodynamic (MHD) formulation aims at modeling the situation where an external magnetic field is applied to flows involving electrically conducting liquids, with the initial magnetic field is known and then evolved over time through …
