Book Description
The purpose of this study was to investigate experimentally two-phase flow in a single vertical channel which was uniformly heated. The channel was a 0.174 inches I.D., 24 inches long, electrically heated stainless steel tube through which distilled water was passed.

Book Description
This volume presents state-of-the-art of reviews in the field of multiphase flow. In focusses on nonlinear aspects of multiphase flow networks as well as visualization experiments. The first chapter presents nonlinear aspects or deterministic chaos issues in the systems of multi-phase reactors. The second chapter reviews two-phase flow dynamics in combination with complex network theory. The third chapter discusses evaporation mechanism in the wick of copper heat pipes. The last chapter investigates numerically the flow dynamics and heat and mass transfer in the laminar and turbulent boundary layer on the flat vertical plate.

Book Description
Multiphase thermal systems have numerous applications in aerospace, heat-exchange, transport of contaminants in environmental systems, and energy transport and conversion systems. A reduced - or microgravity - environment provides an excellent tool for accurate study of the flow without the masking effects of gravity. This book presents for the first time a comprehensive coverage of all aspects of two-phase flow behaviour in the virtual absence of gravity.

Book Description
Experimental two-phase pressure drop data were obtained from a 1/4 x 2 x 60-inch vertical, uniformly heated, test section. The local volume fraction of steam was measured simultaneously with the pressure drop, thus allowing separation of the terms for hydrostatic and acceleration pressure drops from the over-all static pressure drop. The results are expressed in terms of an average two-phase friction factor multiplier, R = DELTA P(sub TPF)/ DELTA P(LO), and are compared with the Martinelli-Nelson correlation, the Lottes-Flinn correlation, and a correlation combining that of Martinelli-Nelson and a flow-rate parameter. The ranges of variables include: pressure from 150 to 600 psig; power density from 17.2 to 94.5 kw/liter of coolant; sub-cooling from 4.8 to 25.7 deg F; exit qualities from 0.009 to 0.065; exit steam volume fraction from 0.19 to 0.77; and velocities from 2.56 to 3.43 fps.

Book Description
Zweiphasenströmungen, insbesondere Wasser/Dampf-Strömungen, sind für die Auslegung und den Betrieb thermohydraulischer Systeme nach wie vor von großem Interesse. Diese Arbeit befasst sich mit der Untersuchung des Druckverlustes und dynamischer Instabilitäten (hier Dichtewellenoszillationen) in Wasser/Dampf-Strömungen mittels zweier unterschiedlicher Ansätze unter praxisnahen Bedingungen. Zum einen wird ein Versuchsstand entwickelt, aufgebaut und in Betrieb genommen, um mit diesem entsprechende Versuche an einem Verdampferrohr durchzuführen. Zum anderen werden dynamische Simulationen mit einem homogenen („mixture flow“) und einem heterogenen („two-fluid“) Strömungsmodell durchgeführt und miteinander und mit den Messdaten verglichen. Die experimentellen und numerischen Ergebnisse lassen sich schließlich in dimensionslosen Stabilitätskarten zusammenfassen, welche die Betriebsgrenzen beschreiben, bei denen Dichtewellenoszillationen in thermohydraulisch ähnlichen Systemen auftreten können.
