The discrete velocity method in plasma physics
The objective of this thesis is to apply a discrete velocity model to kinetic theory problems in plasma physics. Numerical approaches commonly used in kinetic theory are described and compared with the discrete velocity models. The discrete Boltzmann equation (DBE) is a commonly used discrete …

Meshless Discrete Velocity Boltzmann Model for Porous Media Flow
… for addressing computational fluid dynamics: the discrete velocity Boltzmann equation (DVBE) and the localized collocation meshless model with upwinding (U-LCMM). The DVBE is a high-level model that describes the foundations of transport phenomena by addressing the microscale motions of particles …

Perfectly Matched Layer Absorbing Boundary Conditions for the Discrete Velocity Boltzmann-BGK Equation
… work was to extend the PML methodology to the discrete velocity Boltzmann-BGK equation (DVBE) for the case of a horizontal mean flow in two and three dimensions. The proposed extension of the PML has been accomplished in this dissertation. Both split and unsplit PML absorbing boundary …

Arbitrary high order discontinuous Galerkin methods for the shallow water and incompressible Navier-Stokes equations on unstructured staggered meshes
… two-dimensional shallow water equations, the discrete free surface elevation is defined on a primal triangular grid, while the discrete total height and the discrete velocity field are defined on an edge-based staggered dual grid. Similarly, for the two-dimensional incompressible Navier-Stokes …

Seismicity of the Bath County, Virginia locale
… and fixed seismic arrays to develop a crustal velocity model in the Bath County, Virginia locale (June-August, 1982). The results indicate an upper-layer with P and S velocities of 5.45 km/sec and 3.07 km/sec respectively, and a thickness 3 km. Data from the 2 most distant observing stations …

Mesoscopic Numerical Methods for Reactive Flows: Lattice Boltzmann Method and Beyond
… plane, whereas an additional component of the discrete velocity normal to the plane is introduced to discretize the polar angle. The radiative LBM is used to solve a two-dimensional square enclosure bechmark problem. Validation of the model is carried out by investigating the effects of the …
