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 ...
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 ...
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. ...
The effect of surface conditions on nuceate pool boiling heat transfer to sodium
(Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1965], 1965)
A simplified theoretical model for bubble nucleation stability has been proposed, and an approximate stability criterion has been developed. This criterion contains both fluid and surfqce properties, and it predicts that ...
The effect of nonuniform axial heat flux distribution on the critical heat flux
(Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1965], 1965)
A systematic experimental and analytic investigation of the effect of nonuniform axial heat flux distribution on critical heat rilux was performed with water in the quality condition. Utilizing a model which ascribes the ...
A study of boiling water flow regimes at low pressures
(Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1966], 1966)
"A comprehensive experimental program to examine flow regimes at pressures below 100 psia for boiling of water in tubes was carried out. An electrical probe, which measures the resistance of the fluid between the centerline ...
Refrigerant forced-convection condensation inside horizontal tubes
(Cambridge, Mass. : M.I.T. Heat Transfer Laboratory, [1969], 1969)
High vapor velocity condensation inside a tube was studied theoretically. The heat transfer coefficients were calculated by the momentum and heat transfer analogy. The Von Karman universal velocity distribution was applied ...
An experimental and theoretical study of radiative and conductive heat transfer in nongray semitransparent media
(Cambridge, Mass. : M.I.T. Engineering Projects Laboratory, [1969], 1969)
One dimensional temperature profiles and heat fluxes within a slab of molten glass were measured experimentally. The glass slab was contained in a platinum foil lined ceramic tray inside a high temperature furnace. An ...
Forced-convection surface-boiling heat transfer and burnout in tubes of small diameters
(Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1962], 1962)
A basic heat-transfer apparatus was designed and constructed for the study of forced-convection boiling in small channels. The various regions of forced-convection surface boiling were studied experimentally and analytically. ...
Film boiling of saturated liquid flowing upward through a heated tube : high vapor quality range
(Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1964], 1964)
Film boiling of saturated liquid flowing upward through a uniformly heated tube has been studied for the case in which pure saturated liquid enters the tube and nearly saturated vapor is discharged. Since a previous study ...
