Influence of fully miscible lubrication oil on flow boiling of CO₂ inside horizontal evaporator tubes

Influence of fully miscible lubrication oil on flow boiling of CO₂ inside horizontal evaporator tubes PDF Author: Wetzel, Markus
Publisher: KIT Scientific Publishing
ISBN: 3731507277
Category : Chemical engineering
Languages : en
Pages : 452

Book Description
Flow boiling heat transfer, pressure drop and flow pattern of CO?-POE oil mixtures were experimentally investigated in smooth and micro-fin tubes. The POE oil used features full miscibility in the range of operation investigated. The experimental data was evaluated based on mixture properties, used to evaluate and improve established predictive methods. The knowledge obtained contributes to understanding the influence of oil, which is essential for achieving an efficient evaporator design.

Handbook of Evaporation Technology

Handbook of Evaporation Technology PDF Author: Paul E. Minton
Publisher: William Andrew
ISBN: 9781493303335
Category : Technology & Engineering
Languages : en
Pages : 409

Book Description
This excellent volume combines a great deal of data only previously available from many different sources into a single, informative volume. It presents evaporation technology as it exists today. Although evaporation is one of the oldest unit operations, it is also an area with dramatic changes in the last quarter century. Although other methods of separation are available, evaporation remains the best process for many applications. All factors must be evaluated in order to select the best evaporator type. This book will be extremely useful in evaluating and deciding which evaporation technology will meet a particular set of requirements.

Two-Phase Flow, Boiling, and Condensation

Two-Phase Flow, Boiling, and Condensation PDF Author: S. Mostafa Ghiaasiaan
Publisher: Cambridge University Press
ISBN: 9781107431638
Category : Technology & Engineering
Languages : en
Pages : 0

Book Description
This text is an introduction to gas-liquid two-phase flow, boiling and condensation for graduate students, professionals, and researchers in mechanical, nuclear, and chemical engineering. The book provides a balanced coverage of two-phase flow and phase change fundamentals, well-established art and science dealing with conventional systems, and the rapidly developing areas of microchannel flow and heat transfer. It is based on the author's more than 15 years of teaching experience. Instructors teaching multiphase flow have had to rely on a multitude of books and reference materials. This book remedies that problem by covering all the topics that are essential for a graduate first course. Among the important areas that are discussed in the book, and are not adequately covered by virtually all the available textbooks, are: two-phase flow model conservation equations and their numerical solution; condensation with and without noncondensables; and two-phase flow, boiling, and condensation in mini and microchannels.

Organic Rankine Cycle (ORC) Power Systems

Organic Rankine Cycle (ORC) Power Systems PDF Author: Ennio Macchi
Publisher: Woodhead Publishing
ISBN: 0081005113
Category : Technology & Engineering
Languages : en
Pages : 700

Book Description
Organic Rankine Cycle (ORC) Power Systems: Technologies and Applications provides a systematic and detailed description of organic Rankine cycle technologies and the way they are increasingly of interest for cost-effective sustainable energy generation. Popular applications include cogeneration from biomass and electricity generation from geothermal reservoirs and concentrating solar power installations, as well as waste heat recovery from gas turbines, internal combustion engines and medium- and low-temperature industrial processes. With hundreds of ORC power systems already in operation and the market growing at a fast pace, this is an active and engaging area of scientific research and technical development. The book is structured in three main parts: (i) Introduction to ORC Power Systems, Design and Optimization, (ii) ORC Plant Components, and (iii) Fields of Application. - Provides a thorough introduction to ORC power systems - Contains detailed chapters on ORC plant components - Includes a section focusing on ORC design and optimization - Reviews key applications of ORC technologies, including cogeneration from biomass, electricity generation from geothermal reservoirs and concentrating solar power installations, waste heat recovery from gas turbines, internal combustion engines and medium- and low-temperature industrial processes - Various chapters are authored by well-known specialists from Academia and ORC manufacturers

Bubbly Flows

Bubbly Flows PDF Author: Martin Sommerfeld
Publisher: Springer Science & Business Media
ISBN: 3642185401
Category : Science
Languages : en
Pages : 354

Book Description
The book summarises the outcom of a priority research programme: 'Analysis, Modelling and Computation of Multiphase Flows'. The results of 24 individual research projects are presented. The main objective of the research programme was to provide a better understanding of the physical basis for multiphase gas-liquid flows as they are found in numerous chemical and biochemical reactors. The research comprises steady and unsteady multiphase flows in three frequently found reactor configurations, namely bubble columns without interiors, airlift loop reactors, and aerated stirred vessels. For this purpose new and improved measurement techniques were developed. From the resulting knowledge and data, new and refined models for describing the underlying physical processes were developed, which were used for the establishment and improvement of analytic as well as numerical methods for predicting multiphase reactors. Thereby, the development, lay-out and scale-up of such processes should be possible on a more reliable basis.
