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 ...
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 ...
Slug flow
(Cambridge, Mass. : Division of Sponsored Research, Massachusetts Institute of Technology, [1959], 1959)
Introduction: When two phases flow concurrently in a pipe, they can distribute themselves in a number of different configurations. The gas could be uniformly dispersed throughout the liquid in the form of small bubbles. ...
Correlation of maximum heat flux data for boiling of saturated liquids
(Cambridge, Mass. : Massachusetts Institute of Technology, Division of Industrial Cooperation, [1955], 1955)
Liquid and gas distributions in a two-phase boiling analogy
(Cambridge, Mass. : Massachusetts Institute of Technology, Division of Industrial Cooperation, [1958], 1958)
This report contains a description of the design and operation of an experimental appats for the analysis of two-phase flows similar to thom occuwring in boiler tubes at low pressures. Velocity and denuity profiles of ...
Entrance effects in a developing slug flow
(Cambridge, Mass. : Massachusetts Institute of Technology, Division of Industrial Cooperation, [1960], 1960)
The kinetics of a Taylor bubble, as it rises behind a series of other bubbles in a gas-liquid slug flow, have been determined. The rise velocity of a bubble is expressed as a function of separation distance from the bubble ...
The mechanism of void formation in initially subcooled systems
(Cambridge, Mass., M.I.T. Dept. of Mechanical Engineering, [1963], 1963)
When an initially subcooled, water filled system undergoes a transient in heat flux or pressure such that bubbles form, the most important variable which determines the volume of the resulting void is the number of bubbles ...
The correlation of nucleate boiling burn-out data
(Cambridge, Mass. : M.I.T. Division of Industrial Cooperation, [1957], 1957)
A dimensionless correlation is developed for nucleate boiling buzrnout data including the following ranges of variables. Fluids - Water Bensene n - Heptane n - Pentane Ethanol Pressure - 0.0045 to 0.96 of critical pressure ...
The Measurement, interpretation and use of unsteady momentum fluxes in two-phase flow.
(Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1967], 1967)
The steady and unsteady components of the momentum flux in a two-phase flow have been measured at the exit of a vertical pipe by means of an impulse technique using a turning tee and beam. Different electrical filters have ...
