Abstract

The study of the interaction of air flow with a water film is an under-researched topic, and therefore this study is relevant for the academic community. The analysis and modelling results complement existing knowledge and expand the understanding of processes in this area. The purpose of this study was to compare the parameters of the air flow generated in the device for removing water from the surface of the mine hoist rope when changing the shape of the rarefaction chamber, which can increase the efficiency of the device. In the study, a computer experiment was performed to create models of the rarefaction chamber of the device for removing water from the rope surface with different shapes of the device surface. The experiment itself was conducted in SolidWorks Flow Simulation software. The study found that changing the shape of the rarefaction chamber substantially affects the air flow parameters in the device for removing water from the rope surface. At a ratio of D/D1=1.6...2.5, flow stability and effective water removal along the entire length of the rope were observed. Specifically, it was found that the value D/D1=1.6 is particularly optimal, as this pressure is as close as possible to the intensity of water removal, ensuring an even flow distribution and minimal energy consumption. This allows the device to operate at high efficiency, reducing the risk of uneven water removal and increasing the reliability of the lift. The resulting uneven air flow has a negative impact on the integrity of the water film on the rope surface and, as a result, on the removal of water from the surface of the mine hoist rope. The study of this problem allows expanding the understanding of the effect of air flow on the water film on the rope surface and contributes to the development of more efficient water removal devices, which is the practical value of this study
