  • Natural convection and conduction in a vertical annulus with a concentric baffle : a numerical study

    Creator:
    Fishbaugher, Mark J.
    Abstract:
    Analytical and numerical study of steady-state laminar natural convection and conduction has been performed for an enclosure between concentric vertical cylinders. The inner and outer cylinders were isothermal, and the connecting top and bottom walls were adiabatic. A concentric baffle was included in the annulus, and the flow field and...

  • Design and testing of fabric composite heat pipes for space nuclear power applications

    Creator:
    Kiestler, William C.
    Abstract:
    Conventional stainless steel - water and ceramic fabric composite water heat pipes have been built and tested. The tests have been conducted to compare the performance characteristics between conventional and fabric composite heat pipe radiators for space nuclear power heat rejection systems. The fabric composite concept combines a strong ceramic...

  • An investigation of fabric composite heat pipe feasibility issues

    Creator:
    Marks, Timothy S.
    Abstract:
    The design of a fabric composite heat pipe has been completed. It is composed of two end caps, between which a fluid containment liner composed of metal foil and an outer structural layer composed of a ceramic fabric is stretched. The interior of the heat pipe is layered with a...

  • Ultralite copper reflex tube life test and ceramic fabric wicking rate experiments

    Creator:
    Snuggerud, Ross D.
    Abstract:
    This thesis covers two topics. The first subject involves tests run on a ultralite reflux tube supplied by Battelle Pacific Northwest Laboratories (PNL). The second topic involves tests to determine the relative wicking rates of several different fabrics. The ultralite reflux tube supplied by PNL was constructed of copper and...
