Download or read book Two Phase Flow written by Cl Kleinstreuer and published by CRC Press. This book was released on 2003-05-23 with total page 472 pages. Available in PDF, EPUB and Kindle. Book excerpt: This graduate text provides a unified treatment of the fundamental principles of two-phase flow and shows how to apply the principles to a variety of homogeneous mixture as well as separated liquid-liquid, gas-solid, liquid-solid, and gas-liquid flow problems, which may be steady or transient, laminar or turbulent. Each chapter contains several sample problems, which illustrate the outlined theory and provide approaches to find simplified analytic descriptions of complex two-phase flow phenomena. This well-balanced introductory text will be suitable for advanced seniors and graduate students in mechanical, chemical, biomedical, nuclear, environmental and aerospace engineering, as well as in applied mathematics and the physical sciences. It will be a valuable reference for practicing engineers and scientists. A solutions manual is available to qualified instructors.

Download or read book Modelling and Experimentation in Two Phase Flow written by Volfango Bertola and published by Springer. This book was released on 2014-05-04 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This is an up-to-date review of recent advances in the study of two-phase flows, with focus on gas-liquid flows, liquid-liquid flows, and particle transport in turbulent flows. The book is divided into several chapters, which after introducing basic concepts lead the reader through a more complex treatment of the subjects. The reader will find an extensive review of both the older and the more recent literature, with abundance of formulas, correlations, graphs and tables. A comprehensive (though non exhaustive) list of bibliographic references is provided at the end of each chapter. The volume is especially indicated for researchers who would like to carry out experimental, theoretical or computational work on two-phase flows, as well as for professionals who wish to learn more about this topic.

Download or read book A Theoretical Study of the Transient Operation and Stability of Two phase Natural Circulation Loops written by Kermit Garlid and published by . This book was released on 1961 with total page 90 pages. Available in PDF, EPUB and Kindle. Book excerpt: Mathematical models of the time-dependent behavior of two-phase natural-circulation loops were used to predict the operation and to explain the unusual instability sometimes observed. The initial results obtained for a loop similar to the Univ. of Minnesota loop were used to formulate a more complex and accurate model, and the predicted transient behavior was in close agreement with the experimental results from the Minnesota loop. For a 300 psia, high-pressure loop, unstable oscillatory behavior was predicted under certain conditions and stable behavior under others. Closed unstable regions rather than limits were predicted, and the specifications of stability in terms of a single parameter were found to be impossible. The great difference in oscillatory frequencies observed at low and high pressures was found to be due largely to the system geometry. The criterion for the absence of oscillations was found to be similar to one of the criteria for stability of chemical reaction systems.

This book was released on 1962 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: A review is made of some of the experimental data and recent analyses applicable to predicting void fractions with two-phase, steam-water flow through tubes and channels. An empirical equation is presented that closely approximates experimentally measured void fractions in terms of the fluid quality and the ratio of the density of the fluid phases. Correlation of the data is achieved over a range of fluid pressures from 1 to over 135 atmospheres and fluid qualities from 0 to 1.0.

Book excerpt: This book presents concise views of current theories on boiling and two-phase flow and on supercritical heat transfer. The mechanisms of these two modes of heat transfer are compared and contrasted. The theories propose to interpret the observed phenomena from a mechanistic viewpoint, with supporting correlations and equations. Each subsection includes a summary and reference list, and nomenclatures are provided for each major section.
Download or read book Transient Propagation Behavior of Two phase Flow Equations written by and published by . This book was released on 1975 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The capability of published two-phase flow equation sets to predict transient propagation behavior has been studied numerically. The equation sets are those cited by Wallis for separated flow and extensions of those used by Rudinger and Chang for dispersed flow. The primary difference between these two sets is that in the set cited by Wallis, the pressure gradient appearing in each momentum equation is weighted by the phase volume fraction, whereas in the extended Rudinger--Chang set, the pressure gradient appears only in the ''continuous'' phase. The original Rudinger--Chang set had to be modified because it can adequately describe only the transient flow of very dilute suspensions of solids in air. This numerical study shows that pressure pulses propagate at essentially the sound speeds obtained from characteristics analysis for the equation sets investigated. Comparisons of numerical results with experimental air-water pressure propagation data show that only the modified Rudinger--Chang equation set exhibits propagation behavior in good agreement with the experimental observations at low (less than 10 percent) void fractions. None of the equation sets adequately predict the experimental pressure propagation rates in the range of void fractions from 10 to 60 percent where the flow regime was observed to change from bubbly to full slug flow. The modified Rudinger-- Chang set explains an apparent discontinuity in the experimental pressure wave propagation speed at a void fraction of 50 percent if the entire pressure gradient is assumed to be carried by the liquid for less than 50 percent voids and by the vapor for greater than 50 percent voids; however, the magnitude of the calculated discontinuity is greater than the experimental discontinuity.

Download or read book On the Dispersed Two phase Flow in the Laminar Flow Regime written by Novak Zuber and published by . This book was released on 1963 with total page 52 pages. Available in PDF, EPUB and Kindle. Book excerpt: The time-dependent, dispersed, two-phase flow problem for the laminar flow regime is formulated. In agreement with Burgers' description of the flow, the analysis takes into account the effect of both the motion and the presence of other particles. The steady-state solution of the governing set of equations is applied to an analysis of sedimentation and of fluidization (batch, cocurrent and countercurrent). Good agreement with experimental data is shown. The steady-state results give a formulation and a confirmation of the basic premise in the theory of Elgin and Lapidus for vertical two phase flow systems. The theory of kinematic waves proposed by Kynch and by Lighthill and Whitham is used to analyze the transient response, i.e., the diffusion process, and to predict the diffusivity in two-phase flow. The kinematic wave theory is used also to predict the operating limits imposed on the system by the flooding phenomenon. (Author).
