    • The bubbly-slug transition in a high velocity two phase flow 

      Griffith, P.; Snyder, George A. (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. ...
    • Film boiling of saturated liquid flowing upward through a heated tube : high vapor quality range 

      Laverty, W. F.; Rohsenow, Warren M. (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 ...
    • Forced-convection surface-boiling heat transfer and burnout in tubes of small diameters 

      Bergles A. E.; Rohsenow, Warren M. (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. ...
    • The Momentum flux in two-phase flow 

      Andeen, Gerry B.; Griffith, P. (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 prediction of low quality boiling voids 

      Griffith, P. (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 ...
    • Some hydrodynamic characteristics of bubbly mixtures flowing vertically upward in tubes 

      Rose, Sewell C.; Griffith, P. (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 ...
    • A study of boiling water flow regimes at low pressures 

      Fiori, Mario P.; Bergles A. E. (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 ...
    • A study of system-induced instabilities in forced-convection flows with subcooled boiling 

      Maulbetsch, John S.; Griffith, P. (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 ...
    • The transition from the annular to the slug flow regime in two-phase flow 

      Haberstroh, Robert D.; Griffith, P. (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 ...
    • The transition from two phase bubble flow to slug flow 

      Radovcich, Nick A.; Moissis, Raphael. (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 ...
    • Two phase flow in capillary tubes 

      Suo, Mikio; Griffith, P. (Cambridge, Mass. : M.I.T. Heat Transfer Laboratory, [1963], 1963)
      The flow of two phases, gas and liquid, has been studied in horizontal tubes of capillary diameter. The flow has been primarily studied in the regime where the gas flows as long bubbles separated from the wall of the tube ...
    • Two phase pressure drop in inclined and vertical pipes 

      Griffith, P.; Lau, Chun Woon.; Hon, Pou Cheong.; Pearson, John Franklin. (Cambridge : Heat Transfer Laboratory, [1973], 1973)
      A method of calculating the pressure drop in inclined and vertical oil-gas wells is proposed. The data used to establish the method is from a variety of sources but is largely from air and water flowing in systems close ...
    • Unsteady momentum fluxes in two-phase flow and the vibration of nuclear reactor components 

      Yih, Tien Sieh; Griffith, P. (Cambridge, Mass. : M.I.T. Dept. of Mechanical Engineering, [1968], 1968)
      The steady and unsteady components of the momentum flux in a twophase flow have been measured at the exit of a vertical pipe. Measured momentum flux data has been machine processed by standard random vibration techniques ...
