Book Description
Excerpt from Critical Two-Phase Flow for Cryogenic Fluids This work presents a state-of-the-art survey intended to be useful to a designer of equipment involving two - phase flow of cryogenic fluids. It is desirable to assess the probability of critical, or choking, flow in such a system and, if possible, estimate the critical flow rate. The literature is surveyed, primarily since Smith and the predictive results for several analytical models are evaluated and com pared with experimental data. These results are discussed; however, no firm conclusions are reached because, often, the spread of experimental data is equivalent to that of the predictive results from the models.

Book Description
Cryogenic systems that involve two-phase (vapor-liquid) flows are widely used in industries such as aerospace, metallurgy, power engineering, and food production, as well as in high energy physics research. The purpose of this book is to describe characteristic features of cryogenic systems involving two-phase flow, create mathematical models of these systems, and then show how the models may be used to develop optimal designs for practical cryogenic systems. The models are examined using analytical and numerical techniques, and then the predictions are compared to experimental measurements. Since transient phenomena can produce severe and unexpected effects in cryogenic systems, the authors pay particular attention to this important topic. Examples in the book are drawn from cryogenic fluid transport, gasification, and the stabilization of superconducting magnets. Much of this work is related to the development of large Russian systems in the areas of space technology, energy research, and particle physics. This book, the first devoted solely to cryogenic two-phase flow, will be a valuable reference for cryogenic engineers and scientists.

Book Description
Data are presented for the two phase choked flow of three cryogenic fluids - nitrogen, methane, and hydrogen - in four converging-diverging nozzles. The data cover a range of inlet stagnation conditions, all single phase, from well below to well above the thermodynamic critical conditions. In almost all cases the nozzle throat conditions were two phase. The results indicate that the choked flow rates were not very sensitive to nozzle geometry. However, the axial pressure profiles, especially the throat pressure and the point of vaporization, were very sensitive to both nozzle geometry and operating conditions. A modified Henry-Fauske model correlated all the choked flow rate data to within + or - 10 percent. Neither the equilibrium model nor the Henry-Fauske model predicted throat pressures well over the whole range of data. Above the thermodynamic critical temperature the homogeneous equilibrium model was preferred for both flow rate and pressure ratio. The data of the three fluids could be normalized by the principle of corresponding states.

Book Description
The literature summary presents a brief description and discussion of papers on choking, two-phase flow.The papers are arranged with respect to analysis methods and experimental systems.The ide * alized solutions utilize models intended to provide upper and lower limits for the actual flow cases.Charts are presented to provide for rapid determination of choking flow for the choking point condition and for Fanno and isentropic flow for the fluids H2, N2, O2, CCl2F2, CCl3F.A discussion of choking flow and relaxation phenomena is included.(Author).

Book Description
Mehrphasige Strömungen spielen in etlichen Industriezweigen, besonders der Luft- und Raumfahrt und der Energieerzeugung, eine zentrale Rolle. Derart komplexe Strömungsvorgänge sind extrem schwer vorauszuberechnen, zu analysieren und zu testen. Wertvolle Hilfestellungen, die für reale technische Situationen gedacht sind, gibt dieser Band, der auch Quelltexte einschlägiger Computerprogramme enthält. (07/99)

Book Description
Over the past two decades, two-phase flow and heat transfer problems associated with two-phase phenomena have been a challenge to many investigators. Two-phase flow applications are found in a wide range of engineering systems, such as nuclear and conventional power plants, evaporators of refrigeration systems and a wide vari ety of evaporative and condensive heat exchangers in the chemical industry. This publication is based on the invited lectures presented at the NATO Advanced Research Workshop on the Advances in Two-Phase Flow and Heat Transfer. The Horkshop was attended by more than 50 leading scientists and practicing engineers who work actively on two-phase flow and heat transfer research and applications in dif ferent sectors (academia, government, industry) of member countries of NATO. Some scientific leaders and experts on the subject matter from the non-NATO countries were also invited. They convened to discuss the state-of-the-art in two-phase flow and heat transfer and formulated recommendations for future research directions. To achieve these goals, invited key papers and a limited number of contributions were presented and discussed. The specific aspects of the subject were treated in depth in the panel sessions, and the unresolved problems identified. Suitable as a practical reference, these volumes incorporate a systematic approach to two-phase flow analysis.
