Research on the Design Method of Nuclear Heat Exchanger Tube Based on Multi-Objective Optimization

Abstract

In addition to the traditional performance indexes such as heat exchange efficiency and flow resistance, the design of nuclear heat exchange tube needs to take into account the flow noise level index of heat exchange tube at the same time. Therefore, the design of heat exchange tube needs to consider multiple properties such as heat exchange efficiency, flow resistance and flow noise at the same time, which greatly increases the complexity of nuclear heat exchange tube design. In this paper, a design method of low-noise nuclear heat exchange tube is proposed. The design parameters of nuclear heat exchange tube are automatically adjusted based on the coupling of multiple simulation software. The heat exchange efficiency, flow resistance and flow noise of nuclear heat exchange tube are characterized by normalizing the comprehensive evaluation factor of flow and heat transfer and insertion loss, and the optimal design parameters of nuclear heat exchange tube are found through orthogonal test.
