Book Description
Local heat-transfer coefficients in forced convection, downflow boiling, and nonboiling were measured by use of an electrically heated type-304 stainless steel tube (0.7194 in. i.d. x 0.7502 in. o.d. x 68.0 in. long). Average forcedconvection heat-transfer coefficients in turbulent onephase flow and local total pressure gradients in two-phase flow were also determined. Data were obtained for the boiling of distilled water with mass fluxes of 51 to 165 lb/sec sq ft, heat fluxes from 13.8 x 10/sup 3/ to 49.8 x 10/sup 3/ BTU/hr sq ft, pressures at 15.8 to 30.9 psia, and qualities up to 14%. The boiling heat transfer data were compared with the correlations proposed by Mumm, Dengler, Rohsenow, and Grossman and Schrock. No attempt was made to formulate a new correlation because of the limited range of conditions investigated. The nonboiling heat transfer data were compared to the Dittus-Poelter and SiederTate correlations. The local total pressure gradients in two-phase flow were correlated by the Martinelli parameter, X/sub tt/, for turbulent two-phase flow. (auth).

Book Description
An electrically heated, horizontal, Type 347 stainless steel tube was used to obtain local coefficients of heat transfer in the region of net steam generation. The maximum weight fraction evaporated was 0.60. The investigation covered a range of pressure from 45 to 200 psia, of heat fluxes from 50,000 to 250,000 Btu/(hr)(sq ft), and of flow rates from 70 to 280 lb/(sec)(sq ft).

Boiling Heat Transfer And Two-Phase Flow
Author: L S TongPublisher: CRC Press
ISBN: 9781560324850
Category : Science
Languages : en
Pages : 582
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.

Book Description
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.
