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 ...
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 ...
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 ...
The transition from two phase bubble flow to slug flow
(Cambridge, Mass. : M.I.T. Division of Sponsored Research, [1962], 1962)
The process of transition from bubble to slug flow in a vertical pipe has been studied analytically and experimentally. An equation is presented which gives the agglomeration time as a function of void fraction, channel ...
The Momentum flux in two-phase flow
(Cambridge, Mass. : M.I.T. Division of Sponsored Research, [1965], 1965)
The average momentum flux at a section of a pipe with twophase upflow has been measured by the impulse technique. Steamwater and air-water mixtures were tested in one-inch and onehalf inch nominal pipes. Homogeneous ...
The transition from the annular to the slug flow regime in two-phase flow
(Cambridge, Mass. : M.I.T. Division of Sponsored Research, [1964], 1964)
Experiments were conducted to determine the transition from annular to semiannular flow regimes for two-phase, gas-liquid upflow in vertical tubes. The influencesof liquid flow rate, tube diameter, liquid viscosity, surface ...
A study of system-induced instabilities in forced-convection flows with subcooled boiling
(Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1965], 1965)
A combined analytical and experimental program was carried out to investigate the problem of hydrodynamic stability of forcedconvection flows with boiling. The study was restricted to the flow of water in small channels ...
Some hydrodynamic characteristics of bubbly mixtures flowing vertically upward in tubes
(Cambridge, Mass. : M.I.T. Division of Sponsored Research, [1964], 1964)
An investigation of bubbly flow has been conducted in vertical plexiglass tubes using air and water at atmospheric pressure. The bubbly flow pattern is an entrance condition or a non-fully developed flow. A spontaneous ...
The bubbly-slug transition in a high velocity two phase flow
(Cambridge, Mass. : M.I.T. Division of Sponsored Research, [1964], 1964)
A possible mechanism for the transition between bubbly and slug flow is proposed and tested in a simulated slug flow system. No sudden collapse of slug flow with increasing velocity is found and it is concluded that: a. ...
