OPTIMIZATION OF HYDRAULIC RESISTANCE AND IMPROVEMENT OF EFFICIENCY IN HEAT EXCHANGE EQUIPMENT

Abstract. Introduction. This article analyzes methods for reducing hydraulic resistance and improving the efficiency of heat exchange equipment. The study examines methods of changing the flow direction inside pipes using screw, helical, and blade vortex generators. These methods enhance heat transfer efficiency but may increase hydraulic losses. Based on this, recommendations are developed to ensure the compactness of equipment, reduce metal consumption, and optimize hydraulic resistance. The research results can be used to improve energy efficiency in the energy, chemical, and oil industries. Methods and Materials. Heat exchange equipment is widely used in the chemical and oil industries. To improve their efficiency, it is proposed to use flow vortexing and diffuser-convector type channels. Screw, ribbon, and blade turbulators enhance heat transfer but also increase hydraulic resistance. The vortexed flow creates secondary flows, improving heat dissipation. For energy efficiency, these methods can be applied both inside pipes and in the inter-pipe space. Results.The diffuser-convector system consists of sequentially arranged channels. In the diffuser, the turbulence of the flow increases, improving heat transfer, while in the convector, the acceleration of the flow decreases its efficiency. Overall, this system has average hydraulic resistance and high heat dissipation. Heat transfer efficiency depends on the channel length, edge shape, and cross-sectional sizes. In a channel with flat waves, heat transfer is 35-40% higher than in smooth ones. To create compact heat exchange devices, it is important to consider their impact on the cooling system characteristics, such as energy savings and metal consumption. Requirements include minimal size and weight, high efficiency, and low hydraulic losses. However, reducing the size of the device can affect the heat transfer coefficient and strength properties. Conclusion. The results can be used to improve energy efficiency and optimize heat exchange processes. Reducing hydraulic resistance and managing flow increases the efficiency of the equipment. Experiments show that changing the flow direction improves heat transfer. Future research should focus on improving efficiency through innovative materials and new solutions.
