  • 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...

  • On the melting of cylinders and spheres

    Creator:
    Chutia, Bolindra Nath
    Abstract:
    In this thesis we consider boundary and initial value problems associated with the melting of homogeneous cylinders and spheres. The study includes the temperature distribution in cylinders and spheres which are perfectly insulated at the surface and subjected to a heat input respectively along the axis and at the center....

  • On the influence of terrestrial heat flow anomalies on the temperature microstructure at the ocean floor

    Creator:
    Vossler, Donald Alan
    Abstract:
    The effects on the temperature microstructure of terrestrial heat flow and heat flow anomalies at the ocean floor are discussed on the basis of a simple heat diffusion model. The effects on the temperature microstructure of layering of the thermal properties of the ocean are investigated. This is done both...

  • Analytical and numerical continuation methods for conductive temperature fields

    Creator:
    Eggers, Dwight Edward
    Abstract:
    The continuation of conductive temperature fields is being considered. The continuation of a field involves the extrapolation of a field known over a limited domain to an adjacent domain in such a way that it satisfies the heat conduction differential equation and other imposed constraints. Continuations forward in time and...

  • On the theory of heat transport in a semi-infinite solid

    Creator:
    Wong, James Teng
    Abstract:
    The paper concerns itself with the problem of heat transport in a homogeneous, incompressible, isotropic, semi-infinite solid whose boundary is nonstationary. The methods of solution in the one dimensional case are discussed. Numerical examples and a method for arriving at the solutions published by Bailey and Lakin in their paper...

  • 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...

  • 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...

  • 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...

  • Iterative techniques in linearized free surface flow

    Creator:
    Avera, William Edgar
    Abstract:
    The displacement of the free liquid surface in geothermal and hydrologic reservoirs is an important capacitance factor. An iterative approach to determining the drawdown of the free liquid surface for a single sink region in a homogeneous, isotropic, Darcy-type porous mediums is discussed. The iterative approach involves a stepwise adjustment...
