      Shiralkar, B. S.; Griffith, P. (Cambridge, Mass. : M.I.T. Engineering Projects Laboratory, [1968], 1968)
      At slightly supercritical pressure and in the neighborhood of the pseudo-critical temperature (defined as the temperature corresponding to the peak in specific heat at the operating pressure), the heat transfer coefficient ...
    • Dispersed flow film boiling 

      Yoder, Graydon L.; Rohsenow, Warren M. (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. This flow regime can occur in cryogenic equipment, in steam generators, and during nuclear reactor loss of coolant accidents. A theoretical ...
    • Drag reduction in fish-like locomotion 

      Barrett, D.S.; Triantafyllou, M.S.; Yue, D.K.P.; Grosenbaugh, M.A.; Wolfgang, M.J. (Cambridge University Press, 1999)
      We present experimental force and power measurements demonstrating that the power required to propel an actively swimming, streamlined, fish-like body is significantly smaller than the power needed to tow the body straight ...
    • Dryout droplet distribution and dispersed flow film boiling

      Knudsen, Jesper; Hansen, Jacob; Annaswamy, Anuradha M. (2015-04-21)
      The most formidable challenge in assembling a Smart Grid is the integration of a high penetration of renewables. Demand Response, a largely promising concept, is increasingly discussed as a means to cope with the intermittent ...
