Bubble Systems


Book Description

This monograph presents a systematic analysis of bubble system mathematics, using the mechanics of two-phase systems in non-equilibrium as the scope of analysis. The author introduces the thermodynamic foundations of bubble systems, ranging from the fundamental starting points to current research challenges. This book addresses a range of topics, including description methods of multi-phase systems, boundary and initial conditions as well as coupling requirements at the phase boundary. Moreover, it presents a detailed study of the basic problems of bubble dynamics in a liquid mass: growth (dynamically and thermally controlled), collapse, bubble pulsations, bubble rise and breakup. Special emphasis is placed on bubble dynamics in turbulent flows. The analysis results are used to write integral equations governing the rate of vapor generation (condensation) in non-equilibrium flows, thus creating a basis for solving a number of practical problems. This book is the first to present a comprehensive theory of boiling shock with applications to problems of critical discharge and flashing under the fast decompression conditions. Reynolds’ analogy was the key to solving a number of problems in subcooled forced-flow boiling, the theoretical results of which led to easy-to-use design formulas. This book is primarily aimed at graduate and post-graduate students specializing in hydrodynamics or heat and mass transfer, as well as research expert focused on two-phase flow. It will also serve as a comprehensive reference book for designers working in the field of power and aerospace technology.

Adiabatic Waves in Liquid-Vapor Systems


Book Description

The planning for the IUTAM Symposium on Adiabatic Waves in Liquid-Vapor Systems began in May of 1986 in G5ttingen. The Symposium was held in August of 1989 in the Max-Planck-Institut fUr Str5mungsforschung. The invitations to participants suggested that the written papers concern Fast Adiabatic Phase Changes in Fluids and Related Phenomena. Particular topics suggested were: Liquefaction shockwaves and Shock splitting; Evaporation waves; Condensation in Laval nozzles and turbines; Stability in multiphase shocks; Non-equilibrium and near-critical phenomena; Nucleation in dynamic systems; Structure of transition layers; Acoustic phenomena in two phase systems and Cavitation waves. All of these topics should have been treated with emphasis on physical results, new phenomena and theoretical models. Participants from fourteen nations took part in the Symposium and presented papers which were within the range of suggested topics. The organization and execution of the Symposium was performed by the Max-Planck-Institut fUr Str5mungsforschung in G5ttingen. In particular, the meeting has been promoted under the leadership of Professor Dr. E.-A. MUller, who has for many years given his support for international exchanges in science. The detailed work of organization up to and during the Symposium was in large part due to Dr. T. Kowalewski, who served as Symposium Secretary.




Boiling Heat Transfer And Two-Phase Flow


Book Description

Completely updated, this graduate text describes the current state of boiling heat transfer and two-phase flow, in terms through which students can attain a consistent understanding. Prediction of real or potential boiling heat transfer behaviour, both in steady and transient states, is covered to aid engineering design of reliable and effective systems.
