| Izvleček: | Title screen Experimental studies of various microstructures of the surface have been carried out; wettability and heat and mass transfer at non-isothermal evaporation of a drop of water located on a horizontal heated wall have been investigated. Textured surfaces of different topology are obtained by laser exposure. The behavior of heat exchange on a textured surface has been compared with rough (unstructured) wall. It is shown that the instantaneous velocity fields inside the droplet, measured near the structured surface, are inhomogeneous. Heat flux depends on several key factors: droplet diameter, droplet height, convection due to Marangoni forces and convection, associated with surface microstructures. Maximum convection enhancement is registered for the hydrophobic surface. The maximum value of the heat transfer coefficient corresponds to the hydrophobic surface. Heat transfer intensification is about 30% higher than for rough surfaces. Режим доступа: по договору с организацией-держателем ресурса |
