An experimental study of natural convection in air between a vertical isothermal flat plate and a parallel insulated flat plate

Creator:: Kim, Sung-Soo
Abstract:: Natural convection heat transfer in air between two vertical plates 38 by 24 inches was investigated in this work with spacings between the plates of 0.625, 1.0 and 1.75 inches. One plate was isothermal and the other adiabatic. To measure the point velocities in the air layer a very thin...

Heat generation rates of nonfissionable materials in a nuclear reactor environment

Creator:: Zimmerman, Paul James
Abstract:: 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...

The effect of entrance configuration on local heat transfer coefficients in subsonic diffusers

Creator:: Stoffel, Edward Oswald
Abstract:: 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...

Numerical study of natural convection in square partitioned and non-partitioned enclosures

Creator:: Sukkaset, Prasart
Abstract:: 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...

An experimental study of friction factors and mixed convection in the thermal entrance region of vertically narrow, horizontal rectangular channels for different heating conditions and aspect ratios

Creator:: Hong, Seung-Ho
Abstract:: Heat transfer and fluid mechanical behavior of water flowing horizontally in vertically-narrow rectangular channels was studied in this work. Friction factor and Nusselt number variations were determined experimentally for four different wall heating conditions, and for aspect ratios(height to width) of 5, 4, 3, 2, and 1. Wall heating conditions...

Cold trap performance : a general analysis

Creator:: Rothwell, Micheal Olin
Abstract:: 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...

A comparative study of the performance of pin finned heat sinks for cooling electronic components by natural convection

Creator:: Manolescu, Mircea Ion
Abstract:: A study was conducted to determine the heat transfer characteristics of pin finned heat sinks in natural convection. Three pin diameters were studied: 0.238 cm, 0.318 cm and 0.396 cm. The pins were attached to the base in two arrangements, triangular and rectangular, forming a horizontal array. Pin spacing was...
