摘要:

在基于涡轮组和制冷机组联合制冷及气/液两流体喷嘴产生雾化水滴的小型直流式冰风洞中,进行了复合材料部件电加热防冰系统的性能试验。通过改变来流风速、模拟的结冰气象条件、电加热功率及加热方式,得到了不同防冰方式下试验件内的温度分布。结果表明:在本文研究范围内,相同防冰方式下电防冰加热功率随来流风速单调增加;空气温度和液态水含量对电加热功率的影响相互耦合;电加热功率与防护区内的温度及温度梯度成正比;相同防冰负荷下,采用分(多)区加热可以使防护区内的温度及温度梯度分布更合理。

Abstract:

An experiment of electro-thermal anti-icing on a composite assembly is presented. The experiment is run in a small open-circuit icing research tunnel based on a refrigerant system composed of a freon refrigerator and air turbines, and a spray system consisting of air/fluid nozzles. Temperature distribution is provided for different anti-icing methods by altering air speeds, icing conditions and electro-heating powers. The results show that anti-icing electro-heating power increases with air speed, and air temperature and the liquid water content have a coupled effect on the power needed. Temperature and its gradients in the assembly is in proportion to electro-heating power. Multi-zone heating methods lead to reasonable temperature distribution of the assembly under the same anti-icing thermal loads.
