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.

Excerpt from Two-Phase (Liquid-Vapor), Mass-Limiting Flow With Hydrogen and Nitrogen Abstract Experimental data on critical (choked) mass flow in a constant area test section are presented. The data are compared to some simple analytical models which have been recommended for design purposes. The data show the same general behavior as that reported for other non cryogenic fluids. Key Words: Choking, hydrogen, nitrogen, shocks, two-phase flow. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

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.

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.

Critical regimes of two-phase flows with a polydisperse solid phase form the basis of such widespread industrial processes as separation of various powdery materials and minerals dressing. It is impossible to describe such complicated flows analytically. Therefore, this study concentrates on invariants experimentally revealed and theoretically grounded for such flows. This approach can be compared with the situation in gases, where in order to determine principal parameters of their state, one does not need to measure the kinetic energy and velocity of each molecule and find its contribution to the temperature and pressure. These parameters are determined in a simple way for the system on the whole. A novel conception of two-phase flows allowing the formulation of their statistical parameters is physically substantiated. On the basis of the invariants and these parameters, a comprehensive method of estimating and predicting mass transfer in such flows is developed. It is noteworthy that the presented results are mostly phenomenological. Such an approach can be successfully extended to the separation of liquids, gases and isotopes. The book is intended for students and specialists engaged in chemical technology, mineral dressing, ceramics, microelectronics, pharmacology, power generation, thermal engineering and other fields in which flows carrying solid particles are used in the technological process.
