Abstract: Various methods for achieving dropwise condensation (DWC) are reviewed from the point of view of surface science. The objective of the present work is stated. In the experimental study, the surfaces of stainless steel and copper tubes employed were treated with various surface techniques, steam condensation under atmospheric pressure was carried out and steady DWC observed on these surfaces, and the mechanism of DWC formation on the treated surfaces was analysed. Experimental results and photographs of DWC are presented.
