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.

在受控环境条件下向四级轴流式压缩机注水的研究是该研究思想的基础，水通过喷嘴注入轴流式压缩机，并根据空气的温度、压力和湿度进行蒸发。设备由带有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。设备的应用（Großgeräteantrag）包括通过加热和调节环境空气。需要增加驱动装置以及注入水的加热，轴流压缩机本身可供我们使用，目前用于无蒸发注水的研究。水的蒸发，(b) 在不同的入口条件（水量、水压、水温和喷嘴类型）和 (c) 在不同的操作点，例如轴流式压缩机的部分负载，目的是提高知识。压缩机内的蒸发过程，并为仿真模型的验证提供高质量的测试数据。
