The heat-transfer mechanism studied in this experiment was
pool boiling from a flat horizontal surface facing upward with the
bulk liquid at its saturation temperature. The hot-film anemometer
probe was introduced to boiling heat-transfer analysis as a possible
device for counting active nucleation sites and for other investigations
A qualitative evaluation was made of the adherence between
borosilicate glass and the ceramics, steatite and alumina. Three
basic adherence studies were performed.
(1) A comparison between the x-ray diffraction patterns of
the ceramic and the fused glass-ceramic powder mixture was made
to determine if any new compounds were formed...
The effects of round, square, and reentrant entrances on flow
regimes and local heat transfer coefficients were determined using a symmetrical,
plane-wall two-dimensional, subsonic air diffuser with one
of the diverging walls heated and maintained isothermal.
Flow and heat transfer studies were made at total divergence
angles ranging from 0...
The purpose of this thesis work has been the design, construction
and calibration of an instrumented surface for convective heat
transfer studies. The surface is in the form of a flat plate roughly
24 inches wide by 48 inches long. It is made up of 48 individual
cells, laminated side-by-side...
The free convective heat transfer phenomena in air between two
vertical plates 24 by 38 inches spaced 15.895 mm apart, was investigated in this experimental study. One plate was isothermal and, the
A quartz fiber anomometer was used for measuring local
velocities in the air between the vertical...
A constant temperature anemometer, utilizing quartz coated hot
film probes, was used to measure velocities from .1 to 5 cm/sec.
The effects on anemometer performance due to time, reimmersion,
and metallic sensor coatings were examinated by repeated calibrations
of the probes. Contrary to previous published results, calibration
change due to...
Radiation induced heat generation rates of several nonfissionable materials were measured calorimetrically in a nuclear reactor environment. The calorimeter was uniquely designed to allow many materials of grossly different heat generation rates to be measured. heat transfer characteristics of the calorimeter were determined analytically and experimentally. Materials were chosen to...
