TLDR
In this article, the water side heat transfer coefficients without air flow from a single horizontal tube are determined and the total energy dissipated by inside hot fluid when only water is falling is compared with that when both the air and water flow past the tube.About:

Design and Optimization of an Evaporative Condenser: A Detailed Review
TL;DR: In this paper , a literature review performed reveals that by implementing innovative adding-s like water pads, forced induced method, type of nozzles and spray direction, low-finned elliptical tubes, inorganic filler, corrugated plates, multiple pairs of finned channels, internal baffles, air velocity and its direction, L/G ratios results in increasing the performance of the system.

Performance of an Evaporative Condenser: A Review
TL;DR: In this article , a methodology for engineers to follow whilst working on evaporative-cooled heat exchangers is presented, and a method for increasing performance is discovered, and the research with several kinds of evaporative condensers is investigated, it was possible to boost the system's performance by incorporating features like water beds, forced method, exhaust procedure above nozzles, tapering walls to the sump, dome-shaped fans and elliptical (oval) tube designs.

An Experimental Study of Falling Liquid Film Breakdown on a Horizontal Cylinder During Heat Transfer
E. N. Ganic,Michael Roppo +1 more
TL;DR: In this paper, an experimental investigation was conducted with subcooled water film flowing over an electrically heated horizontal cylinder, and the combinations of film flow rate and heat flux at which film breakdown occurs (i.e., dry patches appear on the surface) were determined.
