In this paper, the formation of rising liquid thin film and flow character on the spirally fluted and ribbed surface of a horizontal tube is studied. By analyzing the wetting power leading to the formation of the rising liquid thin film, a mathematical model of one-phase fluid is developed to study the velocity and thickness distribution of the rising liquid thin film during evaporation. Through analyzing the factors affecting the flow character, it is concluded that the spirally fluted and ribbed surface of a horizontal tube is better for the formation of continuous and uniform liquid thin film, and it is also of benefit to flow and heat and mass transfer.
