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

Creator:: Lee, Soon Mo
Abstract:: 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 other adiabatic. A quartz fiber anomometer was used for measuring local velocities in the air between the vertical...

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...

An experimental investigation of natural convection heat transfer from an array of uniformly heated vertical cylinders to mercury

Creator:: Dutton, Jonathan Craig
Abstract:: An experimental investigation was conducted for natural convection heat transfer in an array of uniformly heated vertical cylinders in mercury. The test section consisted of seven electrically heated cylinders of 1.365 inch diameter and 3.825 inch heated length arranged in an equilateral triangular pattern. In order to preclude side flow...

An experimental investigation of natural convection heat transfer from vertical flat plates in mercury

Creator:: White, Donald Henry
Abstract:: Heat transfer from a vertical flat plate in an infinite pool of mercury was investigated. Velocity profiles were measured with a hot-film anemometer and simultaneous temperature profiles measured with thermocouples in this low Prandtl number liquid metal. Constant heat flux plates at Grashof numbers of 9 x 10⁸ and 4...

An experimental investigation of transition pool boiling

Creator:: Aoki, Tadao
Abstract:: The heat-transfer phenomena studied in this work were associated with pool boiling from a flat horizontal surface facing upward with the bulk liquid at its saturation temperature. The analysis of boiling sound and the investigation of the transition boiling mechanism constituted the essence of the present study. The distinctively large...

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...
