N2 - Film-wise condensation takes place in most heat exchangers since this mode is the most stable. Modifying cooled surfaces by applying coatings is trendy method to intensify heat transfer. In this work, a new concept allowing study the influence of surface coating on film-wise condensation is proposed. Reliable thermal data and accurate optical measurements of the condensate thickness distribution were obtained. The correctness of the concept was justified by the demonstration of good agreement between film thickness distributions measured for the uncoated surface and classical Nusselt's theory. Two types of the coating were created and tested as condensers’ surfaces. The first surface has a roughness of 18 µm filled with graphene, did not provide any condensation enhancement. The second coating consisted of the filled roughness of 10 µm and a several graphene layers, demonstrated two times enhancement of the film-wise condensation. For the first time, the impact of the graphene-based coating on film-wise vapour condensation was found when the condensate thickness is comparable with coating. In other words, the level of intensification depends on the technological parameters used to create the coatings.
