Study of Steam Condensation on Vertical Finned Tubes

The article is devoted to the methodology of conducting and processing the results of an experimental study of the process of condensation of water vapour on vertical pipes with specially profiled fins of a heat exchanger. Based on the analysis of heat transfer during laminar condensation of water vapour in the form of a layer of flowing liquid both inside and on the outer surface of vertical pipes with a stationary steam flow, a laboratory installation was developed on which experimental studies were carried out. One of the ways to intensify heat transfer is to optimize the geometry of the heat exchange surface on the condensation side, which reduces the thermal resistance of the wall layers of the resulting condensate. This method is based on increasing the heat exchange area by using specially shaped fins on the surface of the heat exchanger tubes. As a result, an important scientific problem is being solved – disruption of the continuous flow of laminar condensate, which contributes to the direct contact of steam with the cooled surface of the pipe and increases heat transfer. The article describes the methodology of conducting experiments, describes the methods of processing the results obtained, as well as provides calculated data and graphical dependencies illustrating the experimental results.
