Available in PDF, EPUB and Kindle. Book excerpt: Since the petroleum crisis in the 1970s, a lot of effort to save energy was made in industry, and remarkable achievements have been made. In the research and development concerning thermal energy, however, it was clar ified that one of the most important problems was manufacturing con densing systems with smaller size and higher performance. To solve this problem we need a method which synthesizes selections_ of the type of con denser, cooling tube and its arrangement, assessment of fouling on the cooling surfaces, consideration of transient characteristics of a condenser, etc. The majority of effort, however, has been to devise a surface element which enhances the heat transfer coefficient in condensation of a single or multicomponent vapor. Condensation phenomena are complexly affected by a lot of physical property values, and accordingly the results of theo retical research are expressed with several dimensionless parameters. On the other hand, the experimental research is limited to those with some specified cooling surfaces and some specified working fluids. Hence, the basic research of condensation is necessary for criticizing the enhancement effect as well as for an academic interest.

This book was released on 2013-06-29 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: I welcome the opportunity to have my book translated, because of the great emphasis on two-phase flow and heat transfer in the English-speaking world, as related to research, university education, and industrial practice. The 1988 Springer-Verlag edition of "Warmeiibergang beim Kondensieren und beim Sieden" has been enlarged to include additional material on falling film evaporation (Chapter 12) and pressure drop in two-phase flow (Chapter 13). Minor errors in the original text have also been corrected. I would like to express my sincere appreciation to Professor Green, Asso ciate Professor of German at Rensselaer, for his excellent translation and co operation. My thanks go also to Professor Bergles for his close attention to technical and linguistic details. He carefully read the typescript and made many comments and suggestions that helped to improve the manuscript. I hope that the English edition will meet with' a favorable reception and contribute to better understanding and to progress in the field of heat transfer in condensation and boiling. February 1992 K. Stephan Preface to the German-Language Edition This book is a continuation of the series "Heat and Mass Transfer" edited by U. Grigull, in which three volumes have already been published. Its aim is to acquaint students and practicing engineers with heat transfer during condensa tion and boiling, and is intended primarily for students and engineers in mechanical, chemical, electrical, and industrial processing engineering.

Available in PDF, EPUB and Kindle. Book excerpt: In processes with condensation of steam-to-gas compositions or refrigerative agents an intensification of condensation is often required because thermal resistance on the condensation side can be greater than the thermal resistance of the heat transfer wall on the cooling side. In this work, a pair of researchers from the National Technical U. of Ukraine and the State Academy of Refrigeration (Ukraine) provide information about the enhancement of condensation, including research results from the former USSR they feel deserves wider dissemination as well as discussion of different theoretical models of the condensation process.

This book was released on 2018 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Filmwise condensation on a horizontal surface with asymmetric millimeter-sized ratchets and periodically located film drainage pathways in the span-wise direction is analytically and numerically characterized in this research work. The central hypothesis of the proposed research work is that the asymmetry in the surface texture can induce a self-generated directional motion of the condensed vapor. Within the framework of this research work, the hypothesis is tested in three stages. The first stage includes the numerical characterization of the initial transient growth of the condensate film inside a single periodic asymmetric ratchet. The second stage includes testing the validity of a net steady-state preferential drainage of the condensate on a small drainage-pathway-density surface through experimental visualization of the steady-state condensate film and development of a two-dimensional adiabatic analytical model describing the asymmetric steady-state characteristics of condensate film. The third stage comprises of analytical modeling of the condensate film drainage on arbitrarily-shaped smooth periodic surfaces based on orthogonal curvilinear coordinates. The model is utilized to quantify the impact of structural asymmetry introduced to periodic surface profiles on the condensate drainage and surface heat transfer. An optimization of the surface heat transfer rate under the constraints of various surface and fluid parameters is carried out to engender best possible asymmetric surface topologies. Parametric studies are conducted at all stages of the research to evaluate the effects of ratchet pitch, ratchet angles, drainage-pathway-density, orientation of gravity, and Bond number on the condensate film profile. The results from the analysis of experimental visualization, analytical modeling, numerical simulations, and optimization studies in this research work have the potential to enable design of condenser surfaces with novel asymmetric textures, which can be employed in a passive (pump-less) closed-loop microgravity phase-change thermal management system.
