项目摘要

A hybrid gas bearing effectively stabilized by water evaporation from ultra-fine porous medium is proposed and its basic characteristics are clarified by numerical simulation and experiment. The proposed bearing aims to be applied to MGT (Micro Gas Turbine) and has mainly three advantages suitable for application to MGT. The first is the stability improved by water evaporation from ultra-fine porous medium. The second is the effective lubrication by liquid water at the start and stop of the journal rotation. The third is the cooling effect on the high-temperature journal due to water evaporation. Numerical analysis revealed that the hybrid gas bearing is more stable than a conventional gas bearing. The characteristics of the start-up, liquid lubrication and transition state were experimentally examined with heating of journal, and finally the vapor lubrication was achieved.
提出了一种利用超细多孔介质水分蒸发有效稳定的混合气体轴承,并通过数值模拟和实验研究阐明了其基本特性。所提出的轴承旨在应用于MGT(微型燃气涡轮机),并且主要具有适合于应用于MGT的三个优点。第一种是通过水分从超细多孔介质中蒸发来提高稳定性。第二是在轴颈旋转的开始和停止时由液态水进行的有效润滑。第三是由于水分蒸发对高温轴颈的冷却作用。数值分析表明,混合气体轴承比常规气体轴承更稳定。实验研究了轴颈加热条件下的启动特性、液体润滑特性和过渡态特性,最终实现了汽相润滑。
