Investigation of Thermal Engineering Processes in a Plate Heat Exchanger

Abstract

Purpose of research. The aim of the study is to identify vortex formation zones in the modified corrugated channel of a plate heat exchanger using computer modeling to increase the intensification of the heat exchange process.Methods. Plate heat exchangers have a compact design, which significantly saves space on production areas and facilitates the installation and dismantling of equipment. In accordance with the purpose of this work, we solved the problem of creating artificial turbulence of the flow to increase the thermal characteristics.To implement this task, plates have been developed that have a special geometry that creates a turbulent fluid flow in the channels between the plates and increases the heat transfer coefficient. This makes it possible to achieve higher heat exchange efficiency with the same exchange area, which reduces equipment and operating costs.Results. The result of this work is the implementation of a computer model of a modified corrugated channel for visual assessment of the impact of artificially created turbulators on the degree of vortex formation.Conclusion. The introduction of plates, the main heat exchange part of which contains spherical technological wells, makes it possible to increase the efficiency of the heat exchange process by increasing the heat transfer coefficient. In addition, an increase in the heat transfer coefficient will help reduce the metal consumption and the cost of heat exchange equipment.
