摘要

基于波浪转子的气体分压技术(GPD)是一种可同步进行气体压缩和膨胀的潜在技术。本研究为三端口 GPD 装置提出了一种新型波转子弯曲流道(C-FCWR),旨在解决传统宽度恒定直流道(WS-FCWR)的技术难题。我们进行了一系列流体力学和热力学对比分析。对于前弯角为 +10° 的优化 C-FCWR,中压(MP)和低压(LP)端口的流动漩涡产生相当有限,轴功率低至 -0.45 kW,冲击波效率超过 99.8 %,膨胀深度保持在 26.4 K 以上,具有很大的技术优势。就优化后的 C-FCWR 在工作条件下的应用可行性而言,低于 1.2 的压缩比和 1.8 的膨胀比有利于 GPD 设备的整体性能。

Performance enhancement on the three-port gas pressure dividing device by flow channel optimization of wave rotor

Wave-rotor-based gas pressure dividing (GPD) is a potential technology that can synchronously conduct gas compression and expansion. This study, proposes a novel curving flow channel of wave rotor (C-FCWR) for the three-port GPD device, aiming to settle the technical problem of traditional width-constant straight flow channels (WS-FCWR). A series of comparative hydrodynamics and thermodynamic analyses are conducted. For the optimized C-FCWR with a forward-curving angle of +10°, the flow vortex generation in the medium-pressure (MP) and low-pressure (LP) ports is rather limited, the shaft power is as low as -0.45 kW, the shock wave efficiency is beyond 99.8 %, and the expansion depth remains above 26.4 K, proving a great technical advantage. For the application feasibility of the optimized C-FCWR to working conditions, a compression ratio below 1.2 and an expansion ratio of 1.8 are conducive to the overall performance of the GPD device.
