Laminar film condensation of a saturated vapor flowing over a horizontal cylindrical shape
Abstract
The classical problem of the laminar film condensation for a saturated vapor flowing over a cold horizontal cylindrical shape body is investigated. A rigorous formulation of the governing equations for the vapor boundary layer and the liquid film condensate are formulated to include both the gravity-driven body forces and the imposed pressure gradient caused by the flowing vapor. A generalized transformation of the governing equations allows a wide range of both Grashof and Reynolds numbers to be investigated. Numerical solutions in the transformed variables are obtained for both the no-flow and flow conditions over a range of Reynolds numbers and Jacob numbers. Formulation of the governing equations and numerical results are also obtained for the case of a noncondensible gas in the vapor (steam-air mixture). Preliminary findings are examined for the effects of the body shape on the heat transfer performance.
