    Mechanistic Multidimensional Modeling of Forced Convection Boiling Heat Transfer by Michael Z. Podowski, Raf M. Podowski

    Published 2009-01-01
    “…Due to the importance of boiling heat transfer in general, and boiling crisis in particular, for the analysis of operation and safety of both nuclear reactors and conventional thermal power systems, extensive efforts have been made in the past to develop a variety of methods and tools to evaluate the boiling heat transfer coefficient and to assess the onset of temperature excursion and critical heat flux (CHF) at various operating conditions of boiling channels. The objective of this paper is to present mathematical modeling concepts behind the development of mechanistic multidimensional models of low-quality forced convection boiling, including the mechanisms leading to temperature excursion and the onset of CHF.…”

    Calculation of Modes and Power Losses in 0.38 kV Electrical Networks in View of Repeated Earth Connection of Zero Wire by M. I. Fursanov, A. A. Zalatoi, V. V. Makarevich

    Published 2007-10-01
    “…A methodology has been developed to take account of repeated earth connection of a zero wire while making calculation of modes and losses in 0.38 kV and using method of nodal potentials that permits to refine operating conditions of a zero wire. It has been shown that an account of a repeated earth connection of a zero wire exerts an influence on parameters of a mode and power loss in the 0.38 kV network and in this case an influencing force is in direct proportion to unsymmetry degrees of load phase currents and is in inverse proportion to resistance of earthing devices and rods…”
