    PREFACE TO THE ENGLISH EDITION
The foreword of one of the volumes of the Proceedings of the Conference on Mechanics of Multi-Phase Media included a citation from Ecclesiastes: "Two are better than one".
    The progress of gas dynamics of gas-liquid and vapor-liquid media started with attempts to generalize the results of Rieman gas dynamics of a one-phase medium for the case of a mixture of a liquid with gas or vapor bubbles. This mixture was presented as a certain gas having a density close to that of a liquid, and the compressibility of a gas. When solving other problems for such systems, however, the processes of dissipation, mass exchange, and inertia of the combined mass of gas-liquid and vapor-liquid inclusions - which result in the dispersion of the speed of sound - had to be taken into account. Therefore, a generalization of a one-phase Rieman gas dynamics proved to be a failure.
    By the beginning of the 1970s, the problem of creating gas dynamics for two-phase media, which takes into account (at least to a first approximation) the aforementioned effects, was on the agenda. The two-phase medium has proved to be much more complex than one-phase flows so Rieman gas dynamics proved to be a failure.
    The present volume is an attempt to present the fundamentals of gas dynamics of gas-liquid and vapor-liquid media. These studies were initiated by the distinguished thermophysicist, Academician S.S.Kutateladze in Siberia, in the city of Novosibirsk, at the Institute of Thermophysics of the Siberian Branch of the USSR Academy of Sciences. Both the Russian publication and this English translation are a posthumous tribute to his memory.
    The book was translated by an English teacher at the Novosibirsk State University, L.Ya.Yuzina. The publication of the English edition was made possible by the long-term cooperation between thermophysicists of Russia, and publisher Mr. W.Begell.
    Editing of this edition was masterfully done by Prof. A.E.Bergles of the Rensselaer Polytechnic Institute. Prof. E.J.Rymaszewski, also of Rensselaer, assisted with the translation.
    So now, upon the presentation of this English translation, we wish to express our gratitude to all those who have taken part in its publication for their friendly assistance.
    PREFACE
Wave dynamics of two-phase (gas-liquid) systems is a new, intensively developing branch of mechanics of heterogenous systems and thermophysics. Investigations in this field require the involvement of modern data on non-linear wave dynamics, the elaboration of new methods of allowing for interphase interactions, and the practical application of such modern concepts of wave motion as "kinematic" and "dynamic" waves, or "multi-wave models".
    Current interest in such investigations is accounted for by the fact that two-phase flows are the main working fluid in power installations, in equipment for chemical technology, and in various other elements of modern technology. Working processes in the metallurgical, petroleum-extracting, and oil-refining industries, and in cryogenic engineering are accompanied by the formation of vapor-liquid systems.
    Many two-phase systems are well known to be of high compressibility (i.e., the velocity of sound in such systems is small) and, hence, calculations of the dynamics of such media, which move at comparatively small velocities, require gas-dynamical methods. Apart from high compressibility, which makes the medium greatly non-linear, the motion of two-phase system is accompanied by processes of interphase heat and mass exchange, resulting in a considerable dissipation of the medium, while the inertial properties of the gas phase result in the dependence of the velocity of sound on frequency, i.e., in a dispersion of the velocity of sound. Therefore, the methods of conventional gas-dynamics are inefficient for the described specificity of two-phase fluids and give unsatisfactory calculation results. The aim of the investigations presented in this book was to construct non-stationary gas-dynamics that allows, at least to a first approximation, for the peculiarities of two-phase systems listed above. The research done was concentrated on the creation of simple wave models and the corresponding equations, on the solution of these equations, and on the organization of principal physical experiments that help one to gain insight into the nature and basic regularities of gas-dynamical flows. The basic results were obtained in the Institute of Thermophysics of the Siberian Branch of the USSR Academy of Sciences within the period from 1970 through 1984.
