Heat transfer and pressure drop data for high heat flux densities to water at high subcritical pressures
(Cambridge, Mass. : M.I.T. Division of Industrial Cooperation, 1951, 1951)
Local surface ooeffioients of heat t-ansfer, overall pressure drop data and mean friction factor are presented for heat flamms up to 3.52106 BtuAr ft2 for water flowing in a nickel tabe isder the following conditions: mass ...
Dryout droplet distribution and dispersed flow film boiling
(Cambridge, Mass. : Heat Transfer Laboratory, Dept. of Mechanical Engineering, Massachusetts Institute of Technology, [1982], 1982)
Dispersed flow film boiling is characterized by liquid-phase droplets entrained in a continuous vapor-phase flow. In a previous work at MIT, a model of dispersed flow heat transfer was developed, called the Local Conditions ...
The effects of surface instabilities on laminar film condensation
(Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1965], 1965)
Heat transfer rates for laminar film condensation of Freon-1l3 were measured on the underside of horizontal surfaces, inclined surfaces, and vertical surfaces. Several distinct regimes of flow were observed. On the underside ...
The prediction of low quality boiling voids
(Cambridge, Mass. : M.I.T. Division of Sponsored Research, [1963], 1963)
Slug flow theory is used to predict the density in heated channels of various shapes. In order to make this calculation possible, measurements are made of the bubble rise velocity in annuli, tube bundles, and channels. It ...
Model of critical heat flux in subcooled flow boiling
(Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1968], 1968)
The physical phenomenon occurring before and at the critical heat flux (CHF) for subcooled flow boiling has been investigated. The first phase of this study established the basic nature of the flow structure at CHF. A ...
The Effect of vapor subcooling on film condensation of metals
(Cambridge, Mass. : M.I.T. Engineering Projects Laboratory, [1968], 1968)
This work presents an analysis of the interfacial "vapor-condensate" temperature distribution, which includes the effect of subcooling (supersaturation) in the vapor. Experimental data from previous investigators for ...
Burnout in forced convection nucleate boiling of water
(Cambridge, Mass. : M.I.T. Heat Transfer Laboratory, [1957], 1957)
Data are presented for burnout in forced coivection nucleate boiling of water at pressures above 500 psia. A dimensionless correlation is devised for. the M.I.T. data which is found to be valid for certain recent data ...
The effect of surface roughness and waviness upon the overall thermal contact resistance
(Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1966], 1966)
A thermal contact conductance equation was developed which considers both the effect of surface roughness and waviness. It was shown that the overall thermal contact conductance is determined by the roughness at large ...
Void volumes in subcooled boiling systems
(Cambridge, Mass. : M.I.T. Division of Industrial Cooperation, [1958], 1958)
Introduction: Knowledge of the pressure drop in a channel and the resulting flow redistribution is essential in predicting the performance of a nuclear reactor. The pressure drop in a channel which is experiencing boiling ...
Forced-convection, dispersed-flow film boiling
(Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1969], 1969)
This report presents the latest results of an investigation of the characteristics of dispersed flow film boiling. Heat transfer data are presented for vertical upflow of nitrogen in an electrically heated tube, 0.4 in. ...
