RT Journal Article ID 54c6999c3ed69d5c A1 Semenov, V. A1 Nikitin, N. T1 Condensation Heat Transfer on Noncircular Pipes in Stationary Vapor JF Heat Transfer Research JO HTR YR 2008 FD 2008-05-04 VO 39 IS 4 SP 317 OP 326 AB There is a mathematical model for condensation heat transfer on noncircular horizontal tubes with optional cross-section profile. This model is developed taking into account the surface tension force. In this report, we present calculations for local and medium condensate-film thickness and average condensation heat transfer rate for three types of smooth horizontal tubes. The conditions to optimize the cross-section form are determined. These conditions are connected with condensate-film thickness allocation on the condensation surface. In addition, geometric restrictions on the form of these profiles are presented. PB Begell House LK https://www.dl.begellhouse.com/journals/46784ef93dddff27,2d85c52d2708352a,54c6999c3ed69d5c.html
