Solutions to some linear evolutionary systems of equations : study of the double porosity model of fluid flow in fractured rock and its applications.

Creator:: Bodvarsson, Gudrun M.
Abstract:: The present work is a study of three degenerate, linear parabolic systems of equations, each of which represents a version of the so-called double porosity model for underground fluid flows in natural fractured rock. These systems of equations together with initial and boundary conditions describe single-phase flows in fluids, slightly...

The electrical conductivity of Atlantic type pyromagmas from Mount Etna, Sicily

Creator:: Mathews, Frank Samuel
Abstract:: The electrical conductivity of the pyromagmas from the Northeast Crater of Mount Etna, Sicily was measured over the temperature range 1032°C to 1071°C and over the frequency range 1 kHz to 400 kHz. Measurements were made using a four-terminal Wenner array in conjunction with a Wavetek Model 110B portable signal...

Stability of convective flows in porous media

Creator:: Ghandour, Nabil Nassib
Abstract:: The stability of fluids in porous media subject to various physical and geometrical conditions is studied here. Criteria for the onset of convective motions are given in terms of critical temperature gradients or heat sources. The general method used involves the linearization of the field equations about the hydrostatic solutions...

On the reduction and interpretation of ocean-floor temperature and heat flow data

Creator:: Shih, Keh-gong
Abstract:: In this thesis, the interpretation and reduction of ocean heat flow measurements are discussed on the basis of theoretical models. The instrument effect x heat flow measurements is investigated for the case of long period measurements by studying the heat conduction along the measurement probe for both steady and unsteady...

Hydrology and thermomechanics of liquid-dominated hydrothermal systems in Iceland

Creator:: Axelsson, Gudni
Abstract:: Low-temperature hydrothermal activity in Iceland is apparently mostly controlled by dikes and fractures. Conventional methods of production data analysis are not readily applicable in cases of heterogeneous/anisotropic fracture dominated hydrothermal systems. Moreover, the dikes and fractures may control the heat uptake mechanism of low-temperature activity. The free-surface response functions of...

On the numerical interpretation of gravity and other potential field anomalies caused by layers of varying thickness

Creator:: Adotevi-Akue, George Modesto
Abstract:: This thesis involves the interpretation of gravity and other potential field anomalies caused by layers of varying thickness. The partial differential equations of potential field theory are reviewed for gravitational and magnetic force fields. A similar review is carried out for steady-state heat transport and diffusion processes. For the gravitational...

An approach to thermal convection problems in geophysics with application to the earth's mantle and ground water systems

Creator:: Lowell, Robert P.
Abstract:: Two thermal convection problems of geophysical interest are examined, theoretically. First, convection in the earth's mantle is treated on the basis of a one-dimensional 'strip model'. This model results from further simplification of the well known 'Rayleigh model'. For homogeneous, Newtonian fluids, the strip model yields results similar to those...
