The Combined Effect of Vapour Velocity and Condensate Inundation During Condensation on Integral-Fin Tubes: A Theoretical Analysis
نویسندگان
چکیده
This work presents procedures to compute the heat transfer coefficient when downwards flowing pure vapours (or azeotropic mixtures) condense on horizontal integral-fin tubes. At first, single tubes are considered, and the suggested procedure takes shear, gravity and surface tension force into account. The method is compared with a vast data bank demostrating a sound concordance. The second part of the paper considers condensation on tube bundles, also taking the effect of condensation inundation on heat transfer into account. The correlations proposed are compared with available experimental points demostrating satisfactory concordance.

Positive coupling effect in gas condensate reservoirs is assessed through a pure theoretical approach. A combination of linear stability analysis and long bubble approximation is applied to describe gas condensate coupled flow and relative permeability, thereof. The role of capillary number in gas condensate flow is clearly expressed through closed formula for relative permeability. While the m...
