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...

Numerical design of a high-flux microchannel solar receiver

Creator:: Rymal, Charles
Abstract:: This thesis discusses the design of several microchannel solar receiver devices for use in CSP (concentrated solar power) using CFD (computational fluid dynamics) simulations. The goal is to demonstrate that, by taking advantage of the higher heat transfer coefficienct of microchannels, solar receivers can achieve higher efficiency than current receiver...

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 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...

A theoretical study of the radiative contribution to heat transfer between a high-temperature, large-particle gas-fluidized bed and an immersed tube

Creator:: Mahbod, Bahram
Abstract:: An analytical model of the radiative contribution to the total heat transfer between a large-particle (greater than 1 mm) gas-fluidized bed and an immersed horizontal tube is discussed. The model is applied to the case of a bubbling bed and the emulsion phase contribution is obtained from a detailed analysis...

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...

Comparative methods of determining heat transfer coefficients over moist food materials

Creator:: Su, Ainong
Abstract:: Production of surimi represents a potential utilization of a number of low-valued fish species, one of which, Pacific whiting, represents the largest biomass off the West Coast of the United States. However, a protease enzyme softens the fish flesh in Pacific whiting and limits the expansion of surimi production. Many...
