摘要：
Based on the theory of fluid-structure interaction (FSI), the flow characteristics and mechanical properties of torsional flow heat exchanger (TFHX) and cross torsional flow heat exchanger (CTFHX) were numerically studied. The simulation results were compared with the experimental results to verify the reliability of the numerical simulation. The results show that the pressure drop of CTFHX decrease is 30.31-32.56 % lower than that of TFHX, and the heat transfer coefficient is found to lower by 16.8-18.5 %, but the comprehensive performance h/ΔP is increased by 14.8-17.9 %. There is also a higher stress around the baffle holes, and the influence of temperature load on stress is much greater than that of pressure load. Moreover, the linearization results of hazardous locations show that CTFHX has greater stress. This study provides theoretical guidance for the structural optimization and equipment maintenance of heat exchanger.
