Heat transfer characteristics and associated temperature and flow fields for natural convection in two-dimensional, square, partitioned and non-partitioned enclosures have been determined for Grashof numbers ranging from 10³ to 10⁶. The vertical side walls of the enclosure are isothermal with all other surfaces assumed to be adiabatic. An adiabatic partition...
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...
A steady gas convection model of heat transfer to a horizontal
cylinder immersed in a gas fluidized bed is presented. Contributions due to flow within
attached bubbles as well as the interstitial voids are
included. The interstitial flow is approximated as flow within a series
of double cusped channels and...
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...
A cold trap is a device used to remove certain impurities from
a liquid metal by controlled precipitation of such impurities.
An investigation of the thermal characteristics of laminar flow
in two air-cooled cold traps was made. This investigation showed
that the sodium heat transfer rate is a function of...
