This book was released on 1993 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: Analytical studies have been made of laminar film condensation on a horizontal elliptical cylinder in a pure saturated vapor under conditions of free and forced convection. Estimation of interfacial shear stress was made in two ways: the first involving an asymptotic value of the shear stress under conditions of infinite condensation rate and the second based on simultaneously solving the two-phase vapor boundary layer and condensate equations. The latter approach enables the determination of the vapor boundary layer separation point. For the assumption of asymptotic shear stress, effects of surface tension and pressure gradient in the condensate film have been included. At the extremes of eccentricity, corresponding to a circular tube and a vertical plate, the results are compared with theoretical and experimental work of others. Improvement in the condensation heat transfer coefficient was found for elliptical tubes under both free and forced convection conditions when compared to circular tubes of the same surface area. In the latter case, this improvement was due mainly to the reduced drag of the elliptical tube providing a higher vapor velocity for the same pressure drop as that across a circular tube ...

Book Synopsis An Experimental Study of Steam Condensation on a Single Horizontal Tube by : Derry Thomas Pence
Download or read book An Experimental Study of Steam Condensation on a Single Horizontal Tube written by Derry Thomas Pence and published by . This book was released on 1978 with total page 104 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental test facility capable of investigating plain and enhanced horizontal tubes was built. The test facility consists of an electric boiler, test condenser and associated piping for steam, condensate and cooling water. Performance of the test condenser was checked at a steam pressure of 3 psia with cooling water velocities ranging from 5 to 25 ft/sec. Condensation data was obtained for a single, 0.625 inch outside diameter, 90-10 copper-nickel tube in a simualted tube bundle to determine the overall, inside and outside heat transfer coefficients. The overall heat transfer coefficient was determined directly from experimental data, and the Wilson Plot technique was used to determine the inside and outside heat transfer coefficients. The experimentally obtained values for the inside heat transfer coefficient are within 5 percent of the theoretical values predicted by the Sieder-Tate equation. The experimental values obtained for the outside heat transfer coefficient are within 8 percent of the theoretical values predicted by the Nusselt equation. (Author).

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.

Book excerpt: The problem of condensation of steam on a vertical tier of horizontal tubes is investigated by both analytical and experimental methods in this study. A computer program is written to perform the analysis of laminar film condensation on the horizontal tubes. The program is capable to calculate condensate film thickness and velocity distribution, as well as the heat transfer coefficient within the condensate. An experimental setup was also manufactured to observe the condensation phenomenon. Effects of tube diameter and temperature difference between steam and the tube wall on condensation heat transfer have been analytically investigated with the computer program. Experiments were carried out at different inclinations of the tier of horizontal tubes. Effects of the steam velocity and the distance between the horizontal tubes are also experimentally investigated. Results of the experiments are compared to those of the studies of Abdullah et al., Kumar et al. and Nusselt as well as to the analytical results of the present study.
