This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to the complexity of fluid-thermal interactions, heat transfer effects in two-phase fluid systems are not thoroughly understood. One area of particular interest is how large-scale two-phase flow structures, such as vapor slugs, interact with small nucleating bubbles on a heated surface. A research team in the Multiscale Thermal Fluids and Energy Lab at Penn State is interested in expanding knowledge in this area by conducting experimental research on local heat transfer in two-phase slug flow. Several research questions are of interest: How does the wake of a large vapor slug interact with nucleating bubbles on a heated surface? How does an incline of the channel affect these interactions? How does the spacing between vapor slugs affect their interactions with nucleating vapor bubbles? How does vapor slug length develop along a heated channel? How does the incline of the channel affect this development? The answers to these fundamental questions have practical applications in heat exchanger design for power generation systems, water desalination processes, and refrigeration systems. To enable this research, an experimental facility was developed in this thesis research project that is capable of creating the desired two-phase flow conditions. The system is composed of multiple components which provide fluid storage, filtering, pumping, metering, heating, boiling, and pressurization. A preliminary adiabatic test section was installed in order to demonstrate the functionality of the facility. Future research conducted with this facility will involve the development of a more complex test section designed to observe specific flow boiling phenomena. This thesis presents design-related details and choices associated with the development and construction of this facility. Design schematics and specific component selections are described in detail. Operating procedures are presented to ensure the safe operation of the system. Preliminary shadowgraph imagery of slug flow produced by the system is presented. The paper concludes with recommendations for future development and research goals for the experimental facility.

This book was released on 2011 with total page 40 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experimental studies are conducted to predict the phenomenon(s) and to describe some kind of causation. The design of experiment and the experimental facility is a rigorous method. A well designed, manufactured and operated experimental facility is robust under criticism. Thermal hydraulic characteristics of air-water two-phase flows in a vertical tube (poly-dispersed) and also annulus (mono-dispersed) have been subjected to be studied in detail. The hydrodynamics modeling and simulations need a detailed comparison and verification with experimental results. Obviously, a well-designed experimental facility is required to provide a set of highly accurate and reliable data. To do so, two different research facilities have been designed, constructed and operated based on the relevant technical requirements and regulations to conduct the experimental researches.

Available in PDF, EPUB and Kindle. Book excerpt: The approach taken at Lawrence Berkeley Laboratory to obtain relative permeability curves and their dependence on fluid and matrix properties is summarized. Thermodynamic studies are carried out to develop the equations governing two-phase steam/water flow in porous media and to analyze the relationship between mass flow rate and flowing enthalpy. These relationships will be verified against experimental results and subsequently will be used to develop a field analysis technique to obtain in-situ relative permeability parameters. Currently our effort is concentrated on thermodynamic analysis and development of an experimental facility. Some of the findings of the theoretical work are presented and also the design and development effort for the experimental facility is described.

This book was released on 2006 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: 20% of the Nuclear Power Plants are known as Boiling Water Reactors (BWRs). These BWRs have pumps that cool their reactor. In the design of new BWRs, ways to cool the core by a natural circulation flow, without pumps, also called natural circulation BWRs, are being considered. In these new systems, a chimney is installed on top of the core to increase natural circulation flow. A possible disadvantage of natural circulation BWRs might be their susceptibility to instabilities, which could then lead to both flow and power oscillations. The stability features of both natural circulation and forced circulation BWRs have been investigated thoroughly, using dedicated experimental setups, analytical models and numerical codes. We distinguish between pure thermal-hydraulic stability - where the fission power is assumed to be constant - and coupled thermalhydraulic-neutronic stability - where the two-phase mixture in the core influences the fission chain reaction...

Available in PDF, EPUB and Kindle. Book excerpt: The new techniques and instrumentation have been developed and successfully applied to granular shear flows in a Couette apparatus. This apparatus has been designed and constructed to obtain both global quantities and optical measurement of detailed particle movements. Over 48,000 pictures have been taken and analyzed. Concentration, velocity, and granular-temperature profiles have been obtained for the first time. The new physical phenomena observed give many physical insights. The concentration profiles obtained in this present research suggest that the concentration of the particles is not constant across the shear layer. The particle concentration is lower near the both stationary and moving walls and higher near the center. This nonuniformity is the most distinguishable characteristic of granular flows which is different from single-phase fluid flows. The velocity profiles are also not linear across the shear layer. The velocity gradients change from the moving wall to the stationary wall. Both of them differ from the assumptions on which all current constitutive equations are based. Further study is needed to assess the effectiveness of these models. The velocity of the particle at the wall is not the same as the wall velocity, i.e. the non-slip condition does not hold. Hence, traditional non-slip boundary condition cannot be applied to these granular flows. The slip velocity is different for different shear rates and particles under the same physical boundary conditions. This variation provides evidence that the boundary conditions are dependent not only on the walls but also on the interior flow field. Different zones of particle concentration and velocity appear within the same shear layer. The near-wall region has lower concentration of particles and the central part is more densely packed by particles. For non-spherical particles, the velocity profiles are smoother than the corresponding profiles for spherical particles from the moving wall to the stationary wall. For spherical particles the velocity gradient is not even continuous across the shear layer. A negative velocity gradient is observed for both spherical and non-spherical particles. This phenomenon has never been seen in single-phase fluids. Granular temperature, which is a measure of velocity fluctuation of the solid particles, has been obtained for these particles. The profile across the shear layer shows that the granular temperature is larger near both walls and smaller at the center of the shear layer. Thus it is the velocity gradient near the wall that generates the granular temperature.

This book was released on 2000-07-17 with total page 225 pages. Available in PDF, EPUB and Kindle. Book excerpt: The frontier represented by the near solar system confronts humanity with intriguing challenges and opportunities. With the inception of the Human Exploration and Development of Space (HEDS) enterprise in 1995, NASA has acknowledged the opportunities and has accepted the very significant challenges. Microgravity Research in Support of Technologies for the Human Exploration and Development of Space and Planetary Bodies was commissioned by NASA to assist it in coordinating the scientific information relevant to anticipating, identifying, and solving the technical problems that must be addressed throughout the HEDS program over the coming decades. This report assesses scientific and related technological issues facing NASA's Human Exploration and Development of Space endeavor, looking specifically at mission enabling and enhancing technologies which, for development, require an improved understanding of fluid and material behavior in a reduced gravity environment.
