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...
An experimental investigation of the thermohaline, diffusive interface between convecting layers, with heat fluxes more similar to natural fluxes than in previous studies, shows that the formula suggested by Huppert (1971) for the dependence of heat flux on interface stability cannot be extrapolated to stability numbers higher than seven and...
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...
A brief tilt and strain survey was conducted in the Krafla-Namafjall area in the North of Iceland during August of 1979 in order
to study the feasibility of applying solid earth tidal observations
in the exploration of volcanic geothermal systems. The rationale
of the survey was based on the expectation...
The problem of downward continuation of potential fields is
being considered. The basic approach involves computation in real
space using a power series expansion. The computation of the derivatives
required for evaluating the series is carried out on the basis of
two approximation methods, viz. (1) polynomial method, and
(2)...
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...
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...
