  • A numerical analysis of ice fog produced by automobiles

    Creator:
    Nelson, William George
    Abstract:
    A model of an exhaust plume was developed and programmed on a digital computer. The purpose of the model was to predict the concentration and size distribution of ice particles produced from automobile exhaust during arctic conditions. The model accounted for the nucleation, growth, and freezing of the condensed water...

  • Optimization of staged rankine energy conversion cycles for high efficiency

    Creator:
    Simmons, Larry Dean
    Abstract:
    Because of the fuel crisis and problems associated with thermal pollution there is new impetus and urgency for developing more efficient energy conversion systems for power generation. A preliminary analysis was undertaken to determine the potential of staged Rankine cycle systems for substantially higher efficiency. It was necessary to optimize...
