Areas of contact and pressure distribution in bolted joints
(Cambridge, Mass. : M.I.T. Engineering Projects Laboratory, [1970], 1970)When two plates are bolted (or riveted) together these will be in contact in the immediate vicinity of the bolt heads and separated beyond it. The pressure distribution and size of the contact zone is of considerable ...

Bubble growth rates in boiling
(Cambridge, Mass. : Massachusetts Institute of Technology, Division of Industrial Cooperation, [1956], 1956)The conditions determining the growth rate of a bubble on a surface in boiling are considered and a mathematical model framed in the light of these conditions. The growth rate is then calculated for bubbles growing under ... 
The bubblyslug 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. ...

Description of boiling project burnout detector
(Cambridge, Mass. : M.I.T. Heat Transfer Laboratory, [1957], 1957)Introduction: In order to effectively utilize the high heat flux available through the mechanism of nucleate boiling in forced convection heat transfer, it is of primary importance that the maximum flux or "burnout" ... 
The deterioration in heat transfer to fluids at supercritical pressure and high heat fluxes
(Cambridge, Mass. : M.I.T. Engineering Projects Laboratory, [1968], 1968)Introduction: Several supercritical steam generators in the American Electric Power system have shown evidence of tube overheat in the lower furnance at the point where the water bulk temperature is about 670 0 F. The ... 
The deterioration in heat transfer to fluids at supercritical pressure and high heat fluxes
(Cambridge, Mass. : M.I.T. Engineering Projects Laboratory, [1968], 1968)At slightly supercritical pressure and in the neighborhood of the pseudocritical temperature (defined as the temperature corresponding to the peak in specific heat at the operating pressure), the heat transfer coefficient ... 
Dispersed flow film boiling
(Cambridge, Mass. : Heat Transfer Laboratory, Dept. of Mechanical Engineering, Massachusetts Institute of Technology, [1980], 1980)Dispersed flow consists of small liquid droplets entrained in a flowing vapor.
