摘要

为了研究结冰机理和防冰技术，设计并构建了小型低速回流结冰风洞试验系统。在小回流低速风洞中增加了制冷系统和喷雾系统，以实现结冰气象条件。为了验证测试系统的可行性，对测试段的流场均匀性、温度稳定性和液体含水量分布进行了测试和校准。在此基础上，对铝圆柱体、NACA0018翼型和S809翼型进行了结冰试验，并将试验获得的二维冰形与数值模拟软件获得的二维冰形进行了比较。结果表明，在研究的结冰条件和结冰时间下，试验系统参数稳定，实验冰形与模拟冰形一致，能够满足结冰研究的需要。

Research and Development of a Small-Scale Icing Wind Tunnel Test System for Blade Airfoil Icing Characteristics

In order to study the icing mechanism and anti-icing technology, a small low-speed reflux icing wind tunnel test system was designed and constructed. The refrigeration system and spray system were added to the small reflux low-speed wind tunnel to achieve icing meteorological conditions. In order to verify the feasibility of the test system, the flow field uniformity, temperature stability, and liquid water content distribution of the test section were tested and calibrated. On this basis, the icing tests of an aluminium cylinder, an NACA0018 airfoil, and an S809 airfoil were carried out, and the two-dimensional ice shape obtained by the test was compared with the two-dimensional ice shape obtained by the numerical simulation software. The results show that in the icing conditions and icing time studied, the parameters of the test system are stable, and the experimental ice shape is consistent with the simulated ice shape, which can meet the needs of icing research.

期刊介绍： This comprehensive journal provides the latest information on rotating machines and machine elements. This technology has become essential to many industrial processes, including gas-, steam-, water-, or wind-driven turbines at power generation systems, and in food processing, automobile and airplane engines, heating, refrigeration, air conditioning, and chemical or petroleum refining. In spite of the importance of rotating machinery and the huge financial resources involved in the industry, only a few publications distribute research and development information on the prime movers. This journal is the first source to combine the technology, as it applies to all of these specialties, previously scattered throughout literature.
