The influence of gas coflow in a pulse aerosol on evaporation cooling process

Experimental data on the influence of the continuous concurrent air flow on the heat exchange coefficient of a pulse spray and vertical flat heat exchanger are presented. It is shown that continuous air flow not only contributes to cooling but significantly effects the cooling efficiency by including in the heat exchange secondary drops, which originate in the process of bombardment of the cooling film by large drops and their return by the air flow to the surface of dry zones of the heat exchanger.
