摘要/Abstract

摘要：

采用膜片式压力波发生器实验研究连续压力波对横掠管束对流传热的增强效果，分析充气时间、排气时间及减压阀出口压力等参数对压力波特性和传热性能的影响，并评估其能量效益。结果表明高速气体冲击膜片所诱发的瞬态流动及其产生的水锤效应影响压力波的激励，适中排气时间能避免残余气体削弱水锤效应，充排气时间分别为20、80ms是较为合适的。压力波幅值随减压阀出口压力增加呈先增后减趋势。管束平均传热系数在150 kPa时提升较大，为50.13%。强化效果具有空间依赖性，距波源越近增强越显著，管束正面优于背面。能效分析表明，150 kPa工况下能效比达8.75，显示出良好的能量经济性与工程应用潜力。本研究为压力波在强化管束传热领域的工程应用提供了实验依据。

Abstract:

An experimental study was conducted to investigate the enhancement of convective heat transfer in a crossflow tube bundle under continuous pressure waves using a diaphragm-based pressure wave generator. The effects of charging time, exhaust time, and pressure reducing valve outlet pressure on pressure wave characteristics and heat transfer performance were analyzed, and the energy efficiency was evaluated. Results show that the transient flow induced by high-speed gas impacting the diaphragm and its resulting water hammer effect influence pressure wave excitation. A shorter charging time helps form high-intensity pulse waves, while an appropriate exhaust time can avoid residual gas weakening the water hammer effect. A combination of 20 ms charging time and 80 ms exhaust time is relatively suitable. The pressure wave amplitude first increases and then decreases with increasing pressure reducing valve outlet pressure. The average heat transfer coefficient of the tube bundle increases significantly by 50.13% at 150 kPa. The enhancement effect shows spatial dependence: greater enhancement occurs closer to the wave source, and the front side performs better than the back side. Energy efficiency analysis shows an energy efficiency ratio of 8.75 at 150 kPa, demonstrating good energy economy and engineering application potential. This study provides experimental basis for the engineering application of periodic pressure waves in enhancing tube bundle heat transfer.
