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...

A numerical solution for heat transfer to non-Newtonian fluids with temperature-dependent viscosity for arbitrary conditions of heat flux and surface temperature

Creator:: Cochrane, G. F. (Glenn Frank)
Resource Type:: Dissertation
Full Text:: drop is shown to be smaller than for a liquid with no viscosity-tempera- ture dependence. Both the

An experimental study of plane jets issuing at various angles into a cross-flow

Creator:: Hadjilambrinos, Constantine
Abstract:: An experimental study of the properties of plane jets issuing at various angles into a cross-flow of air was conducted to obtain information relating to the momentum diffusion properties of the jet flow in order to provide a background for predicting the feasibility of the preswirl concept of the Volumetric...

Experimental studies of heat transfer with an array of horizontal tubes immersed in a high-temerature fluidized bed

Creator:: Goshayeshi, Ali
Abstract:: An experimental study is described in which time-average local heat transfer coefficients were obtained for arrays of horizontal tubes immersed in a hot fluidized bed. Spatial-averaged heat transfer coefficients, computed from local values, are also reported. Refractory particles with surface mean diameters of 2.14 mm and 3.23 mm were fluidized...

An experimental study of radiative and total heat transfer between a high temperature fluidized bed and an array of immersed tubes

Creator:: Lei, David Hsien-Yu
Abstract:: Experimental data are reported for the time-averaged local radiative and total heat transfer coefficients for both an array of horizontal tubes as well as a single horizontal tube immersed in a large-particle fluidized bed at elevated temperatures. Spatial-averaged heat transfer coefficients computed from the local values, using a simple trapezoidal...

Heat and mass transfer rates associated with the drying of Southern pine and Douglas fir veneer in air and in steam at various temperatures and angles of impingement

Creator:: Laity, Walter William
Abstract:: Southern pine and Douglas fir veneer samples were dried in air under the following conditions: air temperatures were 350, 600, and 750°F; air velocities were 50, 100, and 150 feet per second, and angles of impingement of air against the veneer surfaces were 0°, 45°, and 90°. The resulting drying...

Solid/liquid phase change in small passageways : a numerical model

Creator:: Coven, Patrick J.
Abstract:: During the operation of phase-change ink-jet printers a bubble formation phenomenon often occurs. These bubbles are detrimental to the operation of the printer and substantial efforts are made to remove them. The objective of this research was 1: to develop a fundamental understanding of how bubble or void formation occurs...

On design and field evaluation of the noise control features of the Lake Oswego water treatment plant

Creator:: Reeder, Harry Cromwell
Abstract:: Concern about noise pollution has swept the country. People are conscious of their environment and are trying to preserve or to improve it. When the City of Lake Oswego selected a site for their water treatment plant, they had to assure the neighbors that it would not increase the ambient...

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...

An analytical model of heat transfer to a horizontal cylinder immersed in a gas fluidized bed

Creator:: Adams, Ronald Lynn
Abstract:: 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...
