Characterization of microparticle velocities in converging-diverging nozzle systems
Present day flight vehicles are capable of reaching very high speeds and scientific literature suggests that atmospheric aerosols may cause damage to them. Ongoing work in particle impact damage modeling, aerosol deposition methods, and fundamental studies of particle impact dynamics require …

On the boundary conditions for dissipative particle dynamics (DPD)
… technique that is widely used in simulation of complex fluids. This method simulates the fluid in the scales between microscopic and macroscopic scales. In this thesis, we aim at developing a new wall model in which there is virtually no density fluctuation near the wall boundary. Two test …

Aspects of high field theory in relativistic plasmas
… field physics. We investigate the oscillations of relativistic plasmas using a kinetic description (Chapter II), a macroscopic fluid moment description (Chapter III), a quantum description (Chapter IV as a brief exploration) and Born-Infeld electrodynamics (Chapter V). Using a kinetic …

Microwave emission in a plasma filled nonuniform backward wave oscillator
… industry, and by the military for a variety of purposes including the acceleration of particles in high energy physics, heating of plasma particles, radiation treatment of surfaces in manufacturing, and for electronic warfare in the military. Among the many sources of high power microwaves, …

Evolution of 3-d magnetic topology in flare-productive active regions
… magnetic fields and are the principal source of disturbances that affect space weather. Although physical mechanism and dynamic morphology of flares have been a subject of intense research, many aspects of the flaring process still remain unclear. The objective of this dissertation is to …

Generalised mathematical models for 3D magnetic reconnection at null points: magnetic reconnection at null points
… laboratory and space environments, and often behave in a highly ideal manner. This means that advection of the plasma can store large amounts of energy in the magnetic field. This energy is released when a sudden change in the magnetic topology of the field occurs-facilitated by the …
