Differential equations governing the combined heat and mass
transfer in soils are developed. Transient heat, liquid and vapor
transfer with phase change is considered. The liquid transfer is
treated as a function of the hydraulic conductivity and the gradient of
suction potential. The suction potential is considered a function of...
The results of an experimental and analytical study of deep
submerged multiple-port thermal discharges are presented. The
experimental results include the measured downstream thermal dilution,
width, and centerline trajectory of the buoyant thermal
plume from multiport jets. Independent parameters for which
measurements were obtained include port spacing, discharge Froude
Number,...
Merging isothermal buoyant jets in a crossflow were investigated
experimentally. Jets of salt water were discharged from a constant
head tank into the stagnant tap water. A crossflow was simulated
by towing the discharge ports through the receiving water at desired
speeds. Visualization of the jet cross-sections produced by a...
This study was concerned with the flow of a magnetic self-propelled
ferrohydrodynamic fluid in a horizontal circular tube subjected
to axially varying temperature and magnetic field. The first
phase of the study involved the analytical solution to the governing
equations for the velocity and temperature profiles within the fully
developed...
This paper deals with the thermal decompositon of
wood slabs under fire conditions. The partial differential
equation is solved numerically by the use of an implicit
finite difference method. Wood is treated as two
components, Lignin and Hemicellulose on one side, and
Cellulose on the other side. The chemical reactions...
Dumping drilling mud from offshore drilling rigs into the
ocean could have a negative impact on the marine environment. Due
to this possible impact, the Offshore Operators Committee (OOC) has
deemed it necessary to predict the fate of drilling mud discharged
into the ocean. Through the funding of OOC and...
An experimental study of the short-term fate of a drilling mud discharged into a flowing stratified environment was conducted to determine its dilution and settling characteristics. The drilling mud used in this test had a specific gravity of 1.184 and a composition of 12 percent by weight high-gravity solids (BaSO₄)...
An experimental investigation was carried out to
determine the thermodynamics and fluid mechanics of the
pipe flow of magnetic fluids. A water-based magnetic
fluid was synthesized in the laboratory and its relative
viscosity and magnetic properties were determined
as a function of temperature. A "thermomagnetic pump"
was built and tested...
This thesis presents the results of an experimental
and analytical study of single-port buoyant turbulent jets
discharged into shallow water. The experimental results
include the measured downstream dilution, centerline
concentration and trajectory. Independent parameters
considered were Froude number, submerged depth, discharge
angle and velocity ratio.
Results indicate that decreasing the...
