Creator:: Abel, Kent C.
Abstract:: The next generation of nuclear safety analysis computer codes will require detailed modeling of two-phase fluid flow. The most complete and fundamental model used for these calculations is known as the two-fluid model. It is the most accurate of the two-phase models since it considers each phase independently and links...

Full Text:: Improvement of the One-Dimensional Two-Fluid Model for Horizontal Two-Phase Flow with Model Unification

Creator:: Kim, Dong-Wan
Abstract:: An improved version of the one-dimensional horizontal two-fluid flow model has been developed by incorporating physical terms for gravity and local void fraction profiles. Introduction of an interface mixing layer concept allows the one-dimensional two-fluid model to remain hyperbolic. This will overcomes a major obstacle in using the current one-dimensional...

Creator:: Martin, Mathieu Georges Charles
Abstract:: This thesis addresses numerical simulation of flow maldistribution in microchannels. Microchannels are often associated with two phase-flows which can generate many problems such as plugging the channel or perturbing the flow. In this study we have used CFD and fully resolved technique to simulate what would happen in the case...

Creator:: Pimentel, David Alan
Abstract:: The Oregon State University (OSU) Advanced Plant Experiment (APEX) is a one-fourth height, one-half time scale, reduced pressure integral systems test facility designed to model the long-term cooling capabilities of the emergency core cooling systems of the Westinghouse AP600. This study provides a brief description of the APEX test facility,...

Full Text:: . Title: Two-Phase Fluid Break Flow Measurements and Scaling in the Advanced Plant Experiment (APEX

Creator:: Welter, Kent B.
Abstract:: A literature review of current phase separation publications was conducted. Data sets were collected and compiled into a Two-Phase Flow Separation Database. Examination of this database indicating a need for further investigation into the liquid entertainment phenomena for smaller hot-leg to branch diameters and intermittent flow regimes. A detailed analysis...

Creator:: Young, Eric P.
Abstract:: Two-phase flow in helical conduits is important in many industries where reaction between components, heat transfer, and mass transport are utilized as processes. The helical design is chosen for the effects of secondary flow patterns that reduce axial dispersion, increased heat transfer, and also their compact design. The first is...

Full Text:: Effects of Centrifugal Forces in Air-Water Two-Phase Flow Regime Transitions of an Adiabatic Helical

Creator:: Salakij, Saran
Abstract:: In-situ vapor extraction is performed by applying a pressure differential across a hydrophobic porous membrane that forms a wall of the channel as a means of reducing the local quality of flow boiling within the channel. As the local quality is reduced, the heat transfer capability can be improve while...
