Journal ArticleDOI
Advanced micro-fin tubes for condensation
TL;DR: In this article, the authors developed internal geometries having higher condensation coefficients than existing single-groove micro-fin designs, including both single-helix and cross-grooved surfaces.
Journal ArticleDOI
Particulate fouling of water in tubes having a two-dimensional roughness geometry
Kim Nae-Hyun,Ralph L. Webb +1 more
TL;DR: In this paper, a rationally based fouling model is developed, with experimentally determined sticking probability and deposit bond strength factor, which can predict the fouling behavior of repeated rib tubes.
Journal ArticleDOI
Next Generation Devices for Electronic Cooling With Heat Rejection to Air
TL;DR: In this article, the authors discuss new technology that uses indirect heat removal technology, which involves use of a single or two-phase working fluid to transfer heat from the hot source to an ambient heat sink.
Journal ArticleDOI
A Parametric Analysis of the Performance of Internally Finned Tubes for Heat Exchanger Application
Ralph L. Webb,M. J. Scott +1 more
TL;DR: In this paper, a parametric analysis of the performance of internally finned tubes in turbulent forced convection for application to heat exchangers is presented, where the performance is compared with that of an exchanger having internally smooth tubes.
Journal ArticleDOI
Convective Condensation of Superheated Vapor
TL;DR: In this article, a rationally based method to calculate the condensation coefficient of superheated vapor for condensation inside tubes is presented, and the method is theoretically based, and is applicable to any pure vapor.
