The investigation of water injection into a 4-stage axial compressor with controlled ambient conditions is the foundation of this researchidea. The water injection occurs via nozzles into the axial compressor and evaporates depending on the temperature, pressure and humidityof the air. The test facility consist out of the conditioner for the ambient air with an air heater and the test object itself an axial compressorincluding the drive unit. The application of equipment (Großgeräteantrag) comprises the conditioning of the ambient air by heating and the required increase of the drive unit as well as the heating of the injected water. The axial compressor itself is at our disposal and currently used for research with water injection without evaporation. The conditioning allows investigations of the flow in an axial compressor (a) with evaporation of water, (b) at different inlet conditions (amount of water, water pressure, water temperature and type of nozzles) and (c) at different operating points such as part load of the axial compressor. The objective is to improve the knowledge of evaporation process within the compressor and to provide high quality test data for validation of simulation models.

对一台四级轴流压气机在可控环境条件下的喷水研究是本文研究的基础。水通过喷嘴喷射到轴流压缩机中，并根据空气的温度、压力和湿度蒸发。测试设备由带空气加热器的环境空气调节器和测试对象本身组成，包括驱动单元的轴向压缩机。设备（Großgeräteantrag）的应用包括通过加热和所需的驱动单元的增加以及注入水的加热来调节环境空气。轴流压缩机本身由我们支配，目前用于研究注水而不蒸发。调节允许研究轴流式压缩机中的流动（a）伴随水的蒸发，（B）在不同入口条件（水量、水压、水温和喷嘴类型）下，以及（c）在不同操作点（诸如轴流式压缩机的部分负载）下。其目的是提高压缩机内蒸发过程的知识，并为验证仿真模型提供高质量的测试数据。
