项目摘要
ABSTRACTProposal No. CTS-0320305Principal Investigator: M. Khan, Tuskegee UniversityExtensive efforts are currently underway to develop ultra efficient engine technology. Factors being evaluated are fuel efficiency, noise and environmental impact. The interaction between stator and rotor blades in the compressor (and turbine) greatly influence these factors. Of the many variables, the clearance between the rotor blade tip and the casing has been cited to have the most significant impact on engine fuel efficiency and noise. Extensive experimental and numerical efforts have been directed towards a better understanding of the flow field in the tip region in order to desensitize engine design to the influences of the rotor tip clearance. The recent use of swept blades has introduced further complexities in the flow in this region. Earlier investigations have reported that the axial strain rates generated due to the sweep impact the vortical structures in a blade-hub juncture. The instrumentation procured under this grant will be used to investigate the influence of axial strains rates on the flow physics of the tip clearance region. The 2DPIV system and water tunnel acquired under this proposal will be utilized to map the flow field of such a configuration. Mean and turbulent characteristics of the flow in tip clearance region would be analyzed to understand the physics. The impact of changes in sweep and clearance would also be studied. The influence of relative motion between the blade and simulated casing would also be documented. The availability of this research instrumentation at Tuskegee University will enable the faculty to conduct competitive research. Involvement of students at Tuskegee University in fluid mechanics research and exposure to modern measurement techniques of fluid phenomena would be an extremely beneficial consequence of this instrumentation. Other laboratory courses in the Aerospace Science Engineering Department will also utilize the instrumentation to strengthen theoretical concepts for undergraduates.
摘要建议编号:CTS-0320305首席研究员:塔斯基吉大学M.Khan目前正在进行广泛的努力,以开发超高效发动机技术。正在评估的因素包括燃油效率、噪音和环境影响。压气机(和透平)静、动叶间的相互作用对这些因素有很大影响。在众多变量中,转子叶片尖端和机壳之间的间隙被认为对发动机的燃油效率和噪音有最显著的影响。为了更好地了解叶尖区的流场,为了使发动机设计对转子叶尖间隙的影响不敏感,人们进行了大量的实验和数值计算。最近后掠叶片的使用使这一地区的流动更加复杂。早先的研究已经报道,掠过产生的轴向应变率会影响叶片-轮毂连接处的涡流结构。根据这笔赠款购买的仪器将用于研究轴向应变率对叶尖间隙区域流动物理的影响。根据这项提议获得的2DPIV系统和水洞将被用于绘制这种布局的流场图。为了更好地理解物理过程,需要分析叶尖间隙区流动的平均特性和湍流特性。还将研究清扫和清除变化的影响。叶片和模拟机壳之间的相对运动的影响也将被记录下来。塔斯基吉大学的这种研究工具的可用性将使教职员工能够进行竞争性研究。塔斯基吉大学的学生参与流体力学研究,并接触到流体现象的现代测量技术,这将是该仪器极其有益的结果。航天科学工程系的其他实验室课程也将利用该仪器来加强本科生的理论概念。
