Review article

At present, much attention is paid to an important task in industry, namely, increasing the heat transfer coefficient of heat exchangers with smooth tubes. The article considers one of the techniques to increase the heat transfer coefficient between the heating and heated coolants in a shell-and-tube heat exchanger. The authors propose using the method of increasing the degree of turbulence of the coolant flow by equipping the plate with cylindrical ribs. The results of research carried out by the method of mathematical modeling in the ANSYS Fluent program are presented. Based on the results of mathematical modeling, the optimal rib arrangement has been chosen, which makes it possible to ensure the most complete turbulent flow around the plate. Options for placing ribs with a description of the main thermal and hydraulic characteristics of coolant flows are presented.
