The role of surface conditions in nucleate boiling
(Cambridge, Mass. : Massachusetts Institute of Technology, Division of Industrial Cooperation, [1958], 1958)Nucleation from a single cavity has been stuied indicating that cavity gemtry is aportant in two ways. The mouth diameter determines the superheat nmeded to initiate boiling and its shape determines its stability one 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. ... 
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 nonfully developed flow. A spontaneous ...
